Darkchylde, Demon Within

Whenever you cast a spell from exile or a creature is put into exile, gain 2 life and Darkchylde deals 2 damage to each opponent.

Stepping Discs - Whenever Darkchylde deals combat damage you may pay {b}{r}. If you do, exile Darkchylde and up to one target creature, then return this creature to the battlefield (front face up).
