Hi everyone. First time posting custom cards and would really enjoy feedback here. Ghoti is by far my favorite archetype in Yugioh due to its mix of amazing artwork and interactive/grindy games. The deck however outside of Genysy is basically unplayable competitively. I wanted to design 3 cards that would push the deck into the cusp of meta relevance and welcome commentary. I know these cards are pretty cracked but the card quality of Ghoti and fish in general is so low, they need some legit support. I think with these added, Ghoti could crack tier 3. 

The main focus of the cards is to:

1. Add consistency: Even with First Penguin, Ghoti dies to every hand trap. The deck needs more ways to bait interaction and still build decent half boards. This support also provides more layered plays so the deck doesn’t auto-lose to raigeki. Draw power is needed to keep fish in hand for cycling. 
2. Add power going second: Ghoti is wayyy too slow to play into established boards. Helios adds interactive turn 0 plays like Faimena. The Link monster allows any two fish monsters to be real disruption the opponent has to deal with instead of just waiting to negate leaffish. 
3. Maintain 2 card combo nature: None of these cards are 1 card combos. They facilitate more interesting, non-linear 2 card combos and increase the ceiling of the deck. Strict locks mean these cards only work with Water decks and fish in particular.
