Trample, prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)

Sorcery spells you cast don't trigger this creature's prowess ability.

Whenever a player casts a sorcery spell, you may pay {1}{U/R}. If you do, put a +1/+1 counter on Aegar, Arcane King and draw a card.
