Mardu Siegebreaker (Promo Pack) [Tarkir: Dragonstorm Promos]

Deathtouch, haste

When this creature enters, exile up to one other target creature you control until this creature leaves the battlefield.

Whenever this creature attacks, for each opponent, create a tapped token that’s a copy of the exiled card attacking that opponent. At the beginning of your end step, sacrifice those tokens.
