Plagueclaw Orgrim

Undying Corpse (If this creature is destroyed, instead leave this card on the battlefield, tapped and with no power. It's owner may pay it's mana cost to return it to it's normal state.)
While Plagueclaw Orgrim is an Undying Corpse, any Green lands tapped to pay for it's revival heal it's owner for 1 health. Any Black lands used to pay for it's revival grant Plagueclaw Orgrim +1/+0 until it's owner's next upkeep step.
