Invasion of Tarkir // Defiant Thundermaw

Description

Invasion of Tarkir // Defiant Thundermaw (PMOM-149s foil) is a red double-faced card printed in March of the Machine Promos that enters as a Battle Siege and can transform into a 4/4 Dragon creature. The front Siege lets you reveal any number of Dragons from your hand to deal X+2 damage to another target as it enters, and when defeated it is exiled and may be cast transformed. The back side, Defiant Thundermaw, is a flying, trample Dragon that triggers damage to any target whenever a Dragon you control attacks, supporting aggressive and tribal Dragon strategies.
