Raichu

Electric, Prowess

Exert Raichu: this creature deals damage equal to the mana value of target noncreature spell to any target.

The next time you cast an instant or sorcery, you
may cast an instant or sorcery with mana value equal to or less than that spell’s mana value from your hand without paying its mana cost.

Do this only if this card evolved this turn.
