When Ulder Ravengard, Marshal enters the battlefield, another target nontoken creature you control gains double team (When a creature with double team attacks, if it's not a token, conjure a duplicate of the original into your hand, and then both cards lose double team.) until end of turn. Whenever Ulder Ravengard attacks, conjure (A conjured card is added to the game.) a duplicate of another target nontoken attacking creature into your hand.
