Rajul the Surgeon

Rajul the Surgeon enters the battlefield tapped.
Whenever two or more creature cards are put
into your graveyard from anywhere, you may exile
one of them with a graft counter on it. If you do,
return Rajul from your graveyard to the battlefield.
As long as an exiled creature card with a graft
counter on it has flying, Rajul has flying. The
same is true for deathtouch, lifelink, and menace.
