Destructor Dragon

Green has always been Magic's primary color for blowing up artifacts and enchantments: Naturalize, Nature's Claim, and a long line of one-shot disenchant effects all live here. What this dragon does is fold one of those effects into a body and change when it gets cashed. The destruction trigger fires only on death, which means you do not decide when the removal happens; the opponent does, by deciding whether a 4/4 flier is worth answering at all. Block it, burn it, or send it into a fight, and whatever noncreature permanent they wanted to keep goes with it. That inverts the usual naturalize cadence: instead of holding an answer until the threat appears, you put the threat on the table first and let the answer ride along, uncrackable until the dragon is dealt with. Leave it alone and the flier is a clock; remove it and you eat the trigger. The targeting stays broad (any noncreature permanent, lands included), so the death clause keeps a floor even against a board with nothing exotic to break. It is built for a deck that wants an evasive threat and a piece of interaction it can refuse to spend: the artifact-and-enchantment answer attached to a creature that punishes you for removing it.
