Soul Mending Stag

Soulbond (You may pair this creature with another unpaired creature when either enters the battlefield. They remain paired for as long as you control both of them.)
As long as Soul Mending Stag is paired with another creature, each of those creatures has Spirit transfer (When this creature dies, exile it instead. Search your library for a creature card that shares a colour with it, reveal it, and put it into your hand. Then shuffle your library.)
