{t}: You may sacrifice a creature. If you do, you
may cast that creature from your graveyard for it's mana cost during your next turn. If you cast it this way, it enters the battlefield with a +2/+2 counter. This ability can’t target a creature that has been returned this way in the same game.

Whenever a creature you control dies, gain 2 life.

"What is dead may never die, but rises again, harder and stronger."
