Kris, Spell Prodigy

If you cast an instant or sorcery spell, after it resolves, instead of it going into your graveyard it is treated as a creature with power and toughness equal to its casting cost. If X is in the cost, it enters the battlefield with X +1/+1 counters. Creatures that are an instant or sorcery have, "When this creature does combat damage to a player, you may use its ability as though you cast it from your hand."
