Armed with the menacing claws of the Therizinosaurus, Therizia is one of our only two Main Deck monsters. Able to set a trap of your choice when summoned, she is easily run at as many copies as possible. She is the prime target for our opponent to Imperm/Veiler. While her Normal Summon is powerful, it usually leaves us with a vulnerable monster for our opponent to attack, so be careful.

Recommended ratio: 3

The modern-day Diplodocus. Along with Therizia, Diplos lives in our Main Deck. However, he does not start plays turn 1, as he only dumps a card from the deck. Because of that, you typically do not want to see him in the starting hand. Still, you might want to have some copies of him in your deck due to our monsters' fusion requirements, as well as the only target for Therizia's grave effect.

Recommended ratio: 2

One of our autonomous robots that soar through the sky like a Geosternbergia. Its first effect is counter-productive in the early game, where you want to reduce your life point as low as possible.  In the late game, this effect could be useful for your dead Solemn Strikes, but it is extremely rare as at that point you might have burned your resources already. The burn effect discourages our enemies from using a high ATK monster's effect, which is typically only useful when their LP has become low enough. Due to its specific use, it is mainly only used for fusion fodder when fusing with Frenzy. 

Recommended ratio: 2-3

The queen and the heart of the deck. And maybe the main reason we play this deck. Inheriting the viciousness and adrenaline of the Kentrosaurus, Kentregina gets stronger the closer we are to death's door. Because the game will end when our LP reaches 0, she will never reach 4000 ATK, UNLESS her effect is negated (with Impermanence or Skill Drain alike). Her quick effect is a free real estate, able to copy our archetypal normal trap. In the early game, she is usually summoned first as a stepping stone before going to Rexterm (not only does that give you more mills and bodies, but it also lowers your LP even more!). In the mid and late game, she becomes the grind enabler by copying Brute and Alert, as well as a formidable beater.

Recommended ratio: 2-3

Our big bad boss monster. The first three words of its effect say all. This autonomous T-Rex suppresses the power of our enemies. Its quick effect enables us to ram through almost any monsters that are in Attack Position. As it can solo a lot of decks (especially combo decks), summoning and defending Rex is our usual winning condition. Even at Master, there are still a lot of people who crash their monsters into Rex for no good reason other than scooping afterward. In general, Rex is our wincon.

Recommended ratio: 2-3

The first of our starters. Domain kickstarts our plays by setting up our grave and summoning Kentregina. Note that you can only activate Domain during the Main Phase. Due to turn player's priority, the opponent will have a chance to make a play before we can flip this card. It can also be used to "dodge" effects that target our monsters on the field by using its effect to fuse away the targeted monster.

Recommended ratio: 3

Our other starter. Despite the lower rarity, Frenzy is generally better than Domain (at least in the early game) due to it burning fewer main deck resources, as well as being able to summon Rex right away.  Note that Frenzy can only be activated during the opponent's MP, as opposed to Domain which can be activated on either player's MP. This activation condition still apply even if you copy its effect with Kentregina. 

Recommended ratio: 3

Our simple removal tool. The destroy does not target so it is strong against back row decks. Destroying our monsters as well means that it enables their floating effect. An essential card in Kentregina control. At least one copy is recommended for utility purpose.

Recommended ratio: 1-2

Alert is our recovery tool. This is a good contingency tool in case our Rex is outed, let it be by Super Polymerization, Kaiju, or other methods. If it is still unused, during the opponent's End Phase, we can summon Therizia and Diplos to set up resources for the next turn, as well as options to go to Rank 4 play. Note that it xenolocks us to Dinomorphia, and this restriction still apply even if you copy this effect with Kentregina's effect.

Recommended ratio: 1

The nuts. Intact will negate any monster effects our opponent activates if you control any Dinomorphia card. The Domain or Frenzy you activate in the middle of the chain counts for this. So it can (and mostly will) negate Ash or anything your opponent chains to our starters.  The additional effect is a very huge bonus, making our enemies need to inflict battle damage Floor(2log(LP)) + 1 time to kill us. Well, forgive my math. For instance, for the opponent to kill us at 2000 LP, they have to inflict battle damage 11 times (2000 -> 1000 -> 500 -> 250 -> 125 -> 62 -> 31 -> 15 -> 7 -> 3 -> 1 -> 0)!

Recommended ratio: 1-3

Our Spell/Trap negater. Unlike Intact, it has harder activation conditions. It also destroys your monster, which can typically be good as it triggers our monster's floating effects. Usually only be run at 1 for utility, as generally, Judgment is better.

Recommended ratio: 1

Shell generates a beefy token that shields our monsters for the rest of the turn it is summoned. Unfortunately, the token offers no benefits other than becoming a meatshield or fusion material. Coupled with the awkward activation timing, Shell's relevancy is hard to justify.

Recommended ratio: 0

The card with the most badass artwork unfortunately needs a lot of setups to be live. You need to have a starter and a counter trap in your starting hand for Reversion to be usable. It is actually good as a utility card in a midgame, where you might have several counter traps ready in the graveyard to turn this card into a true omni-negate. However, you will more often than not draw this on your starting hand and at that point, running an additional Strike or Judgment seems to be a better choice.
