Meticulous Artisan

Creature — Djinn Artificer • Mana cost: {3}{R} • Tarkir: Dragonstorm • Common

Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
When this creature enters, create a Treasure token. (It's an artifact with "{T}, Sacrifice this token: Add one mana of any color.")

"It isn't about expression or results. Doing the thing is itself the point."
