Root Greevil

Color-of-your-choice enchantment removal stapled to a beast that has to die to fire it: this is mass enchantment hate dressed up as a creature you might actually cast on curve. The activation asks for the body itself, so the 2/3 spends its life as a deterrent and a delayed Tranquility, sitting on the board until the enchantment problem arrives, then cashing out for a targeted board wipe of one color's auras and global enchantments. The "color of your choice" clause is the interesting bit of restraint: it is not blind symmetry like Tranquility, but it is also not surgical, so you scoop your opponent's enchantments and accept whatever of your own happens to share that color. That makes it a conditional answer worn as a creature, a body that earns its keep in a world where one color leans hard on enchantments and you want the option without committing a noncreature card to it. The cost to deploy the effect (mana, the tap, and the sacrifice) keeps it from being a free repeatable engine; it is one shot, paid for with a creature you already invested in. As a piece of green's long history of enchantment removal, it sits in the strand that hides the answer on a body rather than printing a bare instant, the same impulse that later gave green creatures with stapled artifact and enchantment destruction.
