Filigree Fracture

Naturalize is the floor, and this is what the floor looks like when you bolt a conditional reward onto it. Green's catch-all artifact-and-enchantment answer has always been priced exactly at its function: hit one of two permanent types at instant speed, nothing more. The kicker here is a color-matters rider that pays you a card when the thing you destroyed happens to be blue or black, which is a quiet bit of color-pie politics. Green and white are the colors that get to break artifacts and enchantments, and blue and black are historically the colors most likely to be hiding behind them: a counterspell artifact, a recursion engine, an enchantment that grinds. The draw clause usually rewards catching the right enemy, though nothing stops you from cracking your own blue or black permanent for the card. That makes the card structurally lopsided on purpose. Against the wrong target it is a strictly fair removal spell; against a blue or black permanent it replaces itself, and the spread between those two outcomes is the whole design. It does nothing to widen what green can answer; it only sweetens the cases where green was already the answer to the colors it was built to police.
