Shadow Bishop

Whenever a Shadow Rook or Shadow Knight dies, Shadow Bishop levels up.

Level 1: Shadow Bishop gains +2/+2, lifelink, and flying. Whenever it attacks, target player discards a card.

Level 2: Shadow Bishop gains +4/+4. When Shadow Bishop leaves the battlefield, search your library or outside the game for a card named Shadow Atrium and put it into your hand. If you searched your library, shuffle it.
