Queen Tira of the Honored

Whenever an opponent's creature attacks you, exile that creature. This is not targeting that creature. If its an Angel, that player searches his or her library for all angel cards and removes them from the game, then shuffle his or her library. For each angel exiled this way put a 1/1 Samurai Guard with "Queen Tira of the Honored can't leave the game" and put it onto the battlefield.
