Aegirine Rahn is a decent WATER extender, allowing you to make Chengying or Aegirine Gymir to insulate your plays and help break boards. It's searchable with Icejade Cradle (Which you can also discard for its effect) and serves as a great Small World bridge to almost the entire deck. It's also a great way to get Fish into the GY, especially Tuners. To top it off, if you want to summon the monster you discarded, you can just make Coral Anemone instead. However, requiring a specific discard to summon a monster that doesn't help you start plays is hard to justify. You need to draw Gymir alongside a good starter to get going, which the deck is already hurting for. She's great in builds that go all-in on WATER monsters, but if you're playing supplementary engines like Supay or Superheavy, steer clear.

Rating: Mediocre

Impact :

• Strong Early: Chengying and Gymir apply immense pressure as soon as they hit the board

• Accessible: Can be played at 6 copies alongside Cradle, potentially enabling more Icejades

• Flexible: Recover whatever you discarded with Coral Anemone without your Normal Summon

• Self-Dependent: Because of how her levels match up, she can only really be used as Synchro material with herself

• Bricky: Requiring a WATER discard bottlenecks your hands, especially when WATER lacks good generic techs

THE King Coelacanth, one of the face of Edision and the master of all Fish (After Deep Beyond). Coel is the go to if you want to overwhelm your opponents with a tons of synchros all at once and it's efficiency doesn't stop there, by summoning monsters from your Deck, Coel allow you access to a lot of ressources in a easy way at the cost of their effects being negated, it can even negate targeted effect on himself. All these wonderful things don't come without a drawback however, Coel is a massive handtrap magnet and it's sheer presence will make your opponent pop the ash, not only that but this is also the biggest Nibiru magnet of your Deck. If you can't negate it it's almost always a game loss. Use the big fish at your own risk.

Rating: Viable

Impact :

• Explosive Combo: Coel allow for maximum ceilling combos outputing a lot of Extra Deck monsters with minimum effort 

• Accessible: This card can be searched mid combos with Psiic or Ice barrier which means you never need more than 1 copy in your Deck

• Alternative Use: Coel can be used as XYZ or Link material which means it's odd level is not a total loss

• Built-in Protection: Coel can targeted effects on himself

• Handtrap Magnet : Not only it's a big red flag for your opponent it's also an immediate loss if your opponent has a Nibiru to clear your board

• Discard: Discarding is something you usually don't want to do because this deck lack draw power

• Overextend: More often than not you can get a board of similar value or close to it without Coel 

Kashtira Fenrir is a house of a card that helps you play into anything. It provides board breaking support that Ghoti desperately needs, giving your opponent an asshole to deal with before they start picking apart Ghoti plays. However, playing Fenrir locks you out of strong WATER support cards like Abyss Shark, so the harder you lean into a WATER pile the weaker Fenrir becomes. As a result, Fenrir fits best in engine-focused Ghoti decks that play Supay, Superheavy, or Runick.

Rating: Strong 

Impact:

• Field Presence: The biggest asshole on the block, immediately threatening the board with powerful disruption

• Efficient: Uses no resources to slam down on the board, in fact getting more for follow-up

• Fixes Problems: Ghoti's biggest problems are weak starters and going second, which Fenrir helps alleviate

• Lacks Synergy: Aside from being a good staple, contributes almost nothing to Ghoti's engine, and conflicts with larger ones

• Awkward Level: The best Synchro synergies it has are with Archethys, who isn't frequently played

You may see that Ghoti is a deck focused on banishing its own cards and think that Shifter is an automatic inclusion, but the reality is far more complex. Much of Ghoti's engine - Askaan, Snopios, and Arionpos especially - rely on using the graveyard as a resource, which Shifter completely cuts off. Though those are huge elements of our engine, sometimes summoning Paces and Shif every turn is good enough against a deck that Shifter completely and utterly cripples. As a result, Shifter should only be used when how much it hurts Ghoti is outweighed by how much it hurts your opponent.

Rating: Competitive in Side, Strong in Main

Impact:

• Ends Games Quickly: Sometimes if you drop Shifter in Draw there's nothing your opponent can do

• Contributes to OTKs: Deep Beyond's ATK reaches unfathomable heights under it

• Good Level: In the very rare situation where you have no choice but to Tribute Summon Shifter, being level 6 is great

• Ends Games Quickly: Ghoti shines in the grind game, but our grindiest cards need the GY to function

• Floodgate: Makes you win, but does not make you friends 

THE reason to play a WATER-focused Ghoti build. Abyss Shark not only searches extenders like Silent Angler and White Sunfish, but also helps get plays started by finding Lifeless Leaffish (Especially strong with Paces). Its level may seem awkward, but in combo builds it enables the exceptionally powerful White Aura Monoceros on your way to Archethys, and in every other build it's half of Marincess Coral Anemone, which helps access a Tuner dumped off of Lifeless Leaffish. You can even use it for Kragen! Even though Abyss Shark does nothing on its own, it ties together Fish piles that Ghoti was designed to facilitate.

Rating: Competitive

Impact:

• Synergy: Has a plethora of strong search targets that tie WATER decks together

• Accessible: Searchable off of Psiics and Arionpos

• Follow-Up: You always start Turn 3+ with a WATER on field, so Abyss Shark lets you take control of the game

• Non-Synchro Summons: Enables strong Coral Anemone and Stealth Kragen lines

• Does Your Taxes: Cleans your house too

• Inflexible: Its requirement and lock make it suboptimal in engine-focused builds

• Non-Synchro Summons: Not great for Synchro Summons outside of situational Monoceros lines

• Bricky: With too many high-level monsters, sometimes you can't even get a WATER on field

A level 4 WATER that summons itself on an empty board. What more could you want? Lets you summon Abyss Shark while preserving your normal, and lets you normal a Tuner to summon Arionpos. Unfortunately, Shthana isn't a fish, so it doesn't benefit from other synergies. It's quite literally just a free dude in a deck that desperately needs free dudes.

Rating: Strong

Impact :

• Free Dude: Sometimes you just need a free dude

• Activated Effect: Procs Minairuka! Wow!

• Only Good Early: Not very effective when drawn later into the game

• Limited Synergy: Not being a fish means it can't generate long-term value

If there's any tech card with an argument to be part of the main archetype, it's Lifeless Leaffish. Leaffish send Shif is the deck's sole 1-card combo, which gets to a level 8 Fish Synchro and an Arionpos search on the opponent's turn. Ghotis generally like being in the graveyard anyway, as they can be banished with Askaan, Snopios, and Psiics to continue playing the game. Once you're in the grind game, Leaffish helps you gain the upper hand with much needed recycling and draw power. Despite this, Lifeless isn't extremely powerful independently; Its 1-card combo isn't much, and usually requiring your Normal Summon means it's sometimes challenging to extend further with certain hands. But Lifeless Leaffish is quite literally the best we have.

Rating: Competitive

Impact:

• Resource Generation: One of the only way to generate resources from Deck with your Normal Summon 

• Efficient: Though not potent, Leaffish's 1-card combo is often enough to give you a second turn to really get going

• Easy Template For Extension : Leaffish meet almost every extenders conditions on top of starting plays

• Handtrap Magnet: Sometimes if this gets Ashed or Impermed your turn just ends, and often your game with it

• Slow Recycling: Three fish plus Lifeless is surprisingly hard to get in the GY, so the draw isn't guaranteed

Newest addition to the Fish family, Fishborg Harpooner is one if not the only decent Level 4 tuner that you can access in this deck. His great synergy coupled with his effect allow to Summon cards from your hand that you would usually brick on like Coel or Psiic. While it does improve already existing lines by giving ou alternative access to them it sadly does nothing to help with the deck consistency which we lack of, great card in water focused list but not much anywhere else.

Rating: Viable

Impact:

• Hand Unblocker: Summon cards that would usually be a brick 

• Accessible: Searchable off of Psiics and Arionpos

• Niche use : Being a Level 4 tuners means you use keaf to Synchro summon with it 

• Discard: Discarding is something you usually don't want to do because this deck lack draw power

A searchable floodgate out? Holy moly! Unfortuately, Minairuka is worse than it appears. Being a Quick Effect "When" means your opponent has to not have a response to your effects. Because this is Yu-Gi-Oh!, they usually always do when you're playing into an established board. Not great when Minairuka's primary use is dealing with established boards. In theory, Minairuka can be a solid board breaker and an extender that doesn't lock you like Silent Angler, but in reality it's very difficult to use in reality.

Rating: Mediocre

Impact :

• The Out:  Ghoti's sole out to Skill Drain, and can help deal with TCBOO and Summon Limit as well

• Breaking Boards: A 2-turn negate is nice for dealing with any number of tough boss monsters

• Accessible: Searchable by Abyss Shark and the deck's other Fish searchers

• Bad Conditions: Your opponent effectively has control of when Minairuka is allowed to summon itself, and thus use its effect

• Slow: As an extender, it's allowed to summon itself just a bit too late in the standard combo to be effective 

Silent Angler has way more synergy than cards like Shthana, but requiring a WATER on field is a serious downside for a deck that has trouble starting plays. It's the best search with Abyss Shark bar none, as you can immediately summon it and use it as material for Kragen or Arionpos. But the summon isn't no strings attached; Not being able to summon from hand is significant for cards like Paces, Abyss Keeper, and Kiif. Despite that, Silent Angler is elegant in its simplicity, and is a great extender regardless.

Rating: Competitive

Impact:

• Simple: Easy extender to get on board and start summonin'

• Chainless Special: Lack of activation sets it apart from Shthana and Abyss Shark, which can be negated easily

• Hand Lock: Angler being the last card you can summon from your hand cuts you off of some combolines like Coel

Generic Extender who also provide some milling allowing a potentiel access to more Fish, sadly being held back by the fact that it's a limited card on top of not sharing any Type/Attribute synergy however. Can be used in lists with a high numbers of cards that you want to mill.

Rating : Viable

Impact:

• Deck Milling : Sending fish to the GY let you use them as fuel for other effects and get better access to them

• No Type/Attribute Synergy: Shthana is often just better, situations where Sakitama is superior are very rare

A good extender with no restriction for people who use non-WATER focused builds, the lack of Type/Attribute synergy is a bit of a downside however.

Rating : Viable

Impact:

• Unconditional: The purest Free Guy around, you don't even need an empty field

• Good Level: This plus a Tuner is all you need!

• No Type/Attribute Synergy: Shthana is often just better, situations where Sakitama is superior are very rare

Interesting card, "Hop Ear Squadron" works like a Synchro Summon handtrap allowing you to make any Synchro Summon during your opponent's turn that you could not summon like "Baronne de Fleur" or "Accel Synchro Stardust Dragon". Especially efficiant in a Ghoti-Melffy variant thanks to the Melffy cards who can search "Hop Ear Squadron" making it even better this card can be played instead of a regular handtrap like "Ash Blossom & Joyous Springs" for example.

Rating : Viable

Impact :

• Handtrap : "Dodge" effects of cards like Dark Ruler no More or Evenly Matched since it says in hand 

• Synchro Opener : Give access to Synchro Summon you could get locked out during your turn like "Baronne de Fleur"

• 1 Material : Can only Synchro Summon with the targeted card 

• Not Searchable : Can only be hardraw unless you play the Ghoti-Melffy variant

Usually you Normal Summon a Tuner and then you Special Summon extenders, but "Assault Synchron" offer a different approach. By Special Summoning himself for only 700 LP he has to capabilities of reinforcing plays that start with Lifeless Leaffish by offering a direct access to Arionpos without badly impacting your endboard. His only downside is it's own lack of WATER/Fish synergy as well as conflicting restrictions with Abyss Shark forcing you to use Assault Synchron first. 

Rating : Strong

Impact :

• Field Presence : The only maindeck extender accesible for a cheap condition  

• Synchro Opener : Give more chances of getting access to Synchro Summon you could get locked out usually

• No Type/Attribute Synergy : This can be a big problem if your other extender does not have synergy as well 

• Conflicting Requirements : The restrictions force you to use him first if you have "Abyss Shark" in hand

Mermaid Shark being able to search both Abyss Shark and White Aura Sunfish allow you to get extra consistency for both Pure and White Aura at the cost of being a vulnerable card to Ash and Imperm. Can be used as an alternative Normal Summon to lifeless or the tuners depending on how your list is built.

Rating: Viable

Impact:

• Resource Generation: One of the only way to generate resources from Deck with your Normal Summon 

• Efficient: Though not potent, Leaffish's 1-card combo is often enough to give you a second turn to really get going

• Easy Template For Extension : Leaffish meet almost every extenders conditions on top of starting plays

• Handtrap Magnet: Sometimes if this gets Ashed or Impermed your turn just ends, and often your game with it

Special Summons from the Deck are always really strong. Normal Summoning Beautunaful is essentially Normal Summoning whatever Fish you need to fix your hand... Unless it gets Ashed. Because Tuna leaves you with an empty field, Ash Blossom often leaves you a sitting duck, without even Abyss Shark to help you without a plethora of extenders in hand. An Emergency Teleport is usually too good to pass up, but if you see Tuna in your hand, think twice before firing it off

Rating: Strong

Impact:

• Emergency Teleport: Additional copy of any other Fish starter

• Less Negatable: Banishes for cost on a Summon trigger, so immune to targeted negation

• Accessible: While you can't search it with Abyss Shark, you can search it with Psiics, Arionpos, or Piri Reis Map

• Follow-Up: Searching Tuna off of Arionpos lets you do whatever you want turn 3+

• Ash Magnet: Playing through a negated Beautunaful requires an unbelievable hand (though it is possible)

Good card overall but not mandatory it can banish any "Ghoti" card such as Psiics or Snopios to activate it's effects on banishment or during the next Standby Phase (for the tuners and Kiif). Great if you are on a budget list. 

Rating : Strong

Impact :

• Banish Search : Banish any "Ghoti" to make use of it's effects

• Better Banish : Trigger Psiics and Snopios effects unlike Crossout Designator

• Limited Card : You won't open it consistently 

• Outclassed : Crossout Designator is overall a better card since it also provide protection

Usually played with "Beautunaful Princess" to search it, Piri can also search tuners or kiif depending on the situation providing virtual copies of said cards. However not only does it halve your LP (which can be a determinent during a tournament since the player with the lowest LP lose if time run out) but you are also forced to use this card first during your Main Phase 1 And you are forced to Normal Summon what you searched, meaning it can't be used to add ressources in hand. 

Rating : Strong

Impact :

• Search Tuners: Great combined with "Beautunaful Princess" or if you play a low ammount of tuners in your deck

• Virtual Copy : Additional copy of any Fish monsters with 0 ATK

• Lose to Time : Dividing your LP can have a consequent effect if you play at a tournament

• Fored Normal : What you search you Normal Summon otherwise it's dead in hand

Mostly used with "Ice Barrier" to Search Fish monster, "Foolish Burial Goods" can also be used as a weaker "Terraforming" to send the field spell from your Deck to the GY and then activate it's effect to add it to your hand.

Rating : Mediocre 

Impact :

• Foolish Search : Can send "Ice barrier" for Search or "The Most Distant, Deepest Depths" for pseudo "Terraforming"

• Half a Brick : It's a brick if you hard draw "Ice barrier"

"White Mirror" is a great card to extend or save a combo by Special Summoning a monster you sent to the GY it can even give you an additional copy of whatever you have Special Summoned with it. Be careful however this card can make "Lifeless Leaffish" miss his timing if you decide to add another copy. While remaining a winmore card it has amazing synergy with the "White Aura" engine since it was tailor made to work with the archetype. 

Rating : Mediocre

Impact :

• White Aura Synergy : Massively Raise the ceilling of your play combined with the White Aura engine

• Double Copy : Search an additional copy of what you Summoned giving you more fuel 

• Winmore : It only help when you are already in a good situation 

• Conflicting Timing : It will make Lifeless Leaffish miss his timing if you choose to add another copy 

DRNM is a premiere board breaker, Thanks to Ghoti new support we can finally make use of it. Many decks take advantage of Dark Ruler by picking their board apart during Turn 2 and cleaning up in the subsequent Battle Phase and White Aura Whale help you do just that. A decent card to consider in your Side Deck both as a board breaker and as a Crossout target since DRNM is a devastating card against Ghoti ! 

Rating : Viable

Impact :

• Strong Disruption : Blanket, unrespondable negation

• Monster Shutdown : Completely Shutdown decks relying on a solid board of monsters

• Matchup Dependant : Not every decks rely on monster board 

"Crossout Designator" has an amazing synergy with this Deck not only it can negate annoying cards for us it can also banish our own card to proc their effects the next Standby Phase (mostly for the Ghoti Tuners) acting like a "Gold Sarcophagus" if you are not running it in Pure yet definitively consider doing so. 

Rating : Competitive 

Impact :

• Quick Negate : Protects your plays from hand traps

• Alternative Use : Can banish your own "Ghoti" cards to proc them the next Standby Phase

• Bricky Targets : The more target you run the more bricky the Deck will be

A decent option for WATER heavy decks,  "Ice Barrier" is a great way to Search for high Level Fish monsters since it can easely be sent to the GY with "Foolish Burial Goods" it can also recycle any WATER monster from your GY in case you need it or be used as a defensive card if you hard draw it. However we have better way of accesing our cards nowayday to make it obsolete, consider in budget lists.

Rating : Mediocre

Impact :

• Foolish Search : Search any high Level 5 or Higher Fish monster giving more access to card like King Coelacanth 

• Alternative Use : Can be used as a defense card if draw

• Half a Brick : You want to foolish it not draw it
