Bramble Armor

The self-attaching clause turns this into a green stat boost dressed up as an Equipment. It enters and snaps onto a creature you already control for free, so the two mana buys an immediate +2/+1 with no equip tax at all. That front-loaded attachment is exactly why the equip cost sits at a punishing four: the card would be trivially mobile otherwise, hopping between threats every turn. What the Equipment framing buys instead is durability. The boost outlives its first host, surviving a blocker trade or a sacrifice to be re-equipped onto the next body in a way a one-shot pump spell like Titanic Growth never could. But that permanence comes at sorcery speed only. Without flash, you cannot ambush a combat step by dropping it mid-attack or holding it up on defense; it commits on your main phase like any other permanent, and the value it banks is future value, not surprise value. So the card lands in an odd spot between aura and true Equipment: cheaper to deploy than most gear because it attaches itself, but far costlier to move, trading the mobility that usually justifies the card type for a buff that refuses to die with its carrier. You are paying for staying power, not flexibility, and the four-mana relocation cost is the lever that keeps the trade honest.
