Misthios's Fury

Two mana for three damage to a creature is a fair rate on its own; the second clause is where the design earns its keep. Controlling any Equipment converts a clean removal spell into removal with reach, tacking two damage onto the dying creature's controller. The structural wrinkle is that both halves resolve against a single target creature: you name that creature and collect the player damage as a rider, not as a separate mode you choose between. That keeps the burn honest, because the two-to-the-face is contingent on your board rather than baked into the cost, and it points the card squarely at decks already suiting up a threat and racing: the kind that wants its removal to trade with a blocker and shave the opponent's life total in the same breath. Red has a long tradition of removal that scales off some external condition (a spectacle trigger, a death payoff, an artifact count), and this belongs to that family. In the worst case it is a plain one-for-one kill spell; when your board is set up the way the deck intends, the same card also chips away at the clock you are trying to close. The Equipment requirement is loose enough that a single cheap sword satisfies it for the rest of the game, which is what separates it from a vanilla three-damage instant: the rider is not a build-around, just a small tax you have usually already paid.
