Unbreathing Horde
Creature — Zombie
This creature enters with a +1/+1 counter on it for each other Zombie you control and each Zombie card in your graveyard.
If this creature would be dealt damage, prevent that damage and remove a +1/+1 counter from it.

Rulings
Only one +1/+1 counter will be removed, no matter how much damage is prevented.

If Unbreathing Horde enters from a graveyard, it will count itself when determining how many +1/+1 counters it enters with.
(wotc • 2011-09-22)
If Unbreathing Horde has no +1/+1 counters on it (but its toughness is raised above 0 by another effect), any damage dealt to it will still be prevented, even though no counter will be removed.
