Daemonic Tamer

Whenever a demon enters the battlefield under your control, put a spell counter on Demon Tamer and you may draw two cards. If you do, discard a card.
At the beginning of your combat phase, if there are five spell counters on Daemonic Tamer, remove all counters. If you do, put four 1/1 Black Crow with Flying, Haste and a 4/4 Black Demon with Haste onto the battlefield.
