Alex, Scion of the Inferno

Flying, ward {2}

You may cast legendary Dragon spells as though they had flash.

Whenever you cast a Dragon spell, Alex deals damage equal
to that spell's mana value to a target creature or planeswalker an opponent controls.

Sacrifice a nontoken creature: Add two mana of any combination of colors. Spend this mana only to cast a Dragon spell or to activate an ability of a Dragon.
