Gwyn, Lord of Cinder

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

{r/w}: Gwyn gains first strike until end of turn.

Whenever Gwyn deals combat damage, you may
cast a sorcery spell from your hand with mana value
less than or equal to that damage without paying its
mana cost.

[Ken, Burning Brawler]
