So this is a really difficult and intricate combo, just watch my videos of it on youtube because the description here won't help much.
The idea is you survive and cycle until Smooth Soloist on turn 7-8, then with a Zevi on board, you counterfeit copies 0 mana Veteran Investigators and then infinitely play 0 mana Veteran Investigators to mill out your opponent. (When a player draws through their entire deck they lose automatically). This win condition will often kill your opponent on turn 8-9.
Zap is guaranteed to draw into valuable combo pieces of Rummage of Counterfeit Copies, which is why we don't run other cheap spells.
When you're hitting your infinite combo, Coral Creatures actually gives you +1 mana, which is essential to infinitely being able to play your entire deck on one turn.
