Calandra, the Unfathomable

Deathtouch, intimidate, trample.

{b/g}{u/b}{1}: Destroy a target creature and put a black and green 1/1 zombie into the battlefield.

At the start of your upkeep, place a phage counter on a target permanent. Each creature your opponent controls receives -1/-1 for every phage counter on it. Meanwhile, each creature you control gains +1/+1 for every phage counter on it. If a noncreature permanent has two or more phage counters, destroy it.
