Valkor, the Necro-Tyrant

Flying, haste
Whenever Valkor, Necro-Tyrant enters the battlefield or attacks, exile up to two creatures
from a graveyard. For each creature exiled
this way, put a +1/+1 counter on it and create
a 2/2 black zombie token, tapped and attacking.
Even death is not an excuse to rest under his
servitude
