Mehdjed, Undying

Undergrowth - When Mehdjed, Undying enters
the battlefield, create a 0/0 green-black Zombie
creature token, and put a +1/+1 counter on it
for each creature card in your graveyard.
If Mehdjed, Undying would be exiled, put it in
its owner's graveyard instead. You may cast this
card from the graveyard.
