Brain of Cthulhu

When Brain of Cthulhu enters the battlefield, create two 3/3 Crimson Eye creature tokens named Creeper Swarm, which cannot attack alone.
Brain of Cthulhu cannot take any damage until both Creeper Swarms leave the battlefield. When this happens, Brain of Cthulhu gains First Strike, Haste, and Shroud.
