Steelclaw, Junamar Defender

Trample, first strike
When a creature you control dies, reveal the top card of your library. If its a creature and its converted mana cost is less then or equal to the creature that died converted mana cost, you may cast it without paying its mana cost.
Whenever you cast a noncreature spell, each opponent loses life equal to its converted mana cost. Put a +1/+1 counter on Steelclaw, Junamar Defender equal to the amount of life lost this way.
