Mutation Chamber

{3}, {t}: Replicate target creature. (Create a token
that's a copy of it, except it's an artifact in addition to
its other types. That token gains haste. Exile it at the beginning of the next end step.)
Whenever you replicate a creature, it gets a +1/-1 counter.

face-to-face. Fortunately, he didn't specify whether you should be alive for that or not."
