I have played against a maralen deck and it just got killed everytime because everyone always tutors up answers and combo pieces themselves and if they can combo out faster then you are completely fucked

Two cards is all it took.

Yeah but it's no infinite combo, by the time you get that combo off any krenko or animar deck worth it's salt will have already killed you

on turn 4? I highly doubt that.

you'd be surprised especially with maralen allowing everyone to tutor i have done turn 4 kozilek and emrakul in a duel commander match i have seen krenko decks go infinite as early as turn 3 it's really hard to beat those kind of decks out especially when you give them tutor
