Interesting. Why do you think CCYB's deck needs aflatoxin? (and maybe jade shield)
I could go with a shield, then filling the screen with malignent cells...But with only 1 death in the field does it do anything? The deck has nothing else that kills. That means the creatures drawn before the screen fills all stay and do their damage...
i could spampost tons of screenshot showing just how awesome aflatoxin is in CCYB
the main thing is, aflatoxin - the card is powerful on its own
it does more than just kill a creature
the only reason you dont see it much more in a typical rainbow setup is because of one card in particular, bonewall
jade shield is added as the 3rd shield because it works well with aflatoxin
but jade shield itself is also great against decay, octane and dream catcher (not that great against osiris though)
increasing the win % against them tremendously due to built-in PA and reflect damage ability
just to prove a point :-
