Playing against AI3, the Entropy-death guy. After some turns he plays the combo: Schrodinger's cat, two vultures, some soul catchers, a graveyard and a bonewall. I have only 4 creatures on the field, so if I break the wall after some time, I'd be dead because of his output damage. He plays butterfly effect on the cat (and I have only pendulums and pillars as permanents) so I can easily win after a couple of turns.
