Rennala, Carion Queen

Whenever you cast a non-creature spell, Rennala deals damage equal to the mana cost to any target.

Whenever you cast a non creature spell with mana cost 4, create three 1/1 wolf tokens; mana cost 5 create a 2/2 assassin token; mana cost 6 create a 3/4 giant token; mana cost 7 create a red 4/4 dragon with flying.

Tokens created this way have haste and are exiled at the next end steps
