Enlightened Maniac

Four mana buys two bodies, and the better stats live on the half whose color you don't control: a 0/2 that walls but never threatens, plus a 3/2 colorless Eldrazi Horror that arrives off the enter-the-battlefield trigger. That second body is the reason to run it. The 0/2 frame is what the design pays for the two-for-one: you are buying the Horror at near-retail and getting a defensive afterthought stapled on, not a creature that pulls weight on both sides of combat. The colorless token is what elevates this above vanilla value: it triggers anything watching for Eldrazi or Horrors entering, and it doubles your creature count on a single card, which is what makes it a tribal enabler rather than a body with a body attached. Worth keeping the math honest, though: the token is not a card, so it feeds nothing that counts what your spells leave in the graveyard, and once it dies it ceases to exist rather than sticking around as fuel. What it does feed is anything that converts bodies into value: sacrifice outlets, token payoffs, count-the-creatures triggers. Designed as common-rarity material for an Eldrazi-and-Horror board-building strategy, it reads as filler right up until you remember that two creatures entering off one card is precisely the kind of fuel those engines were built to eat.
