Cell, Parasitic Bio-Android

Inherit — When Cell wins a fight against a creature, exile it under cell. (When a creature fights, blocks, or is blocked and doesn't die while the other creature does, that creature wins the fight)

Evolution — Cell gets +1/+1 for each creature exiled under it, and has the abilities of each creature exiled under it.

{x}{b/g}, Cell fights target creature, where X is that creatures power.
