White Aura offer a big ceilling on top of perfect synergy with no Normal Summon involved, at the cost of cutting your Extra Deck from all non-WATER monsters. Sardine and Sunfish work in tandem to Special Summon and treating themselves as Tuners when needed allowing to easely Synchro Summon into Arionpos or Porpoise. This engine is held back by the fact that it's a 2 card combo which means you have to get access to both cards. White Reincarnation and Abyss Shark help to mitigate the issue but sometimes it's just not enough, at least sardine can be used alone for Links plays or Synchros in rare occasions.
Impact :
Raise the Ceilling : Offer better maxiumum potential to the Deck
Perfect Synergy : All of the White Aura cards can be used as fuel for your Ghoti monsters once they have done their jobs
No Normal : Doesn't use your Normal Summon
Alternative Use : Cards can be used for Links/XYZ Summons
Reduced Options : White Sardine will lock you out of non-WATER Extra Deck monsters
2 Card Combos : Sunfish is a brick alone and Sardine does not combos with a lot of other cards
You activate "White Sardine" effect to send a copy of "White Sardine" to the GY as well as Special Summoning the Sardine who activated said effect, then you activate "White Sunfish" to Special Summon the Sardine in your GY and himself. When it's done you activate the "White Sardine" effect that was Special Summoned from the GY to treat it as a tuner. From there you are able to go into Arionpos or "White Porpoise" depending on what your gameplan is.
"White Reincarnation" is only there as an additional way to search for the White Aura cards.
White Sardine send another copy of itself to the GY and then Special Summon itself
White Sunfish Special Summon the Sardine in your GY and then Special Summon himself (don't forget to treat the Sardine summoned from the GY as a Tuner)
From there you can go into White Porpoise or Arionpos depending your gameplan/hand
Depending on your hand you have multiples options of banishment :
You can banish a Ghoti tuner from your Deck if you only have 1 accesible
You can banish Snopios to add it to your hand if you have a Fish monster in the GY.
You can banish Psiics, banish a Fish to special summon Psiics then add Superancient Deepsea King Coelacanth.
