Creature — Elemental Warlock Villain, {2}{R}
Oracle Text
Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
Whenever a source you control deals noncombat damage to one or more of your opponents during your turn, you create a 1/1 red Elemental creature token. This ability triggers only once each turn.
