Mephit's Enthusiasm

Sorcery

Mephit's Enthusiasm deals 4 damage to target creature or planeswalker. If excess damage was dealt this way, you get a boon with "When you cast your next creature spell, it perpetually gets +X/+0, where X is the amount of excess damage dealt this way." (Perpetual effects that are given to cards are permanent regardless of what zone those cards are in and what zone they move to.)
