Styrmir, the Storm Tyrant

Flying, haste
Whenever one or more dragons you control
attack, exile that many cards from the top of your
library, you may cast a noncreature spell from
among them without paying its mana cost.
Whenever you cast a noncreature spell from
anywhere other than your hand, create a X/X
Red Dragon Elemental creature token with
Flying, where X is that spell's mana cost.
