Telum's Awakening

Search your library for any creature card with
mana cost equal to X and put it onto the
battlefield under your control. You gain
half X life and put one-third X 1/1 black imp
creature tokens with flying onto the battlefield
under your control, rounded down each time.

smiled and nodded. "I'm going to make sure of that."
