Moon Girl and Devil Dinosaur
Two effects that read like they belong to different decks, stapled onto one three-mana body. The artifact trigger is a Simic-flavored engine: every artifact you play refills your hand, capped at one draw per turn so it wants a steady drip of cheap artifacts rather than a storm turn. That cap is what makes the top half hum. The 6/6 transformation keys off your second draw each turn, and the artifact ability is a natural way to manufacture that draw on schedule. So the card's two halves feed each other: play an artifact, draw your second card, and the 2/2 swells into a trampling 6/6 for the turn. It is a rare instance of a creature that builds its own beatdown condition out of its own value engine, then hands you the payoff in the same sequence.
The friction is that the transformation is temporary and per-turn, so the beefy body is a window rather than a state; the 6/6 resets at cleanup, and you have to re-trigger the draw every turn to keep swinging as a threat. That pushes the card toward a low, repeatable artifact curve and cheap card-draw to guarantee the second draw lands before combat rather than after. Read it less as a beater and more as a card-advantage machine that occasionally punches for six, with the punch timed entirely by how you sequence your draws.
