The Thing

Eternal (Whenever this creature dies, return it onto the battlefield tapped under it's owner's control at your end phase.)
The Thing keeps counters on it in graveyard too.

Whenever a creature is sacrificed or The Thing dies, put an aberration counter on this card.

When there are ten or more aberration counters on The Thing, it gains +7/+7, lifelink and fear.

For each aberration counter after the tenth, this card gets +1/+1.
