Battlemage's Bracers

Rings of Brighthearth compressed onto a single body, with the tradeoffs that implies: cheaper to fire (one generic mana per copy instead of two), but locked to whatever creature is wearing it rather than doubling any ability at the table. That narrowing is the whole design. The equipment lives entirely on activated abilities that aren't mana abilities, which means it does nothing for triggers or spells, and it wants a creature whose single activation already generates enough value to be worth resolving twice: a token-maker, a tutor-on-a-stick, a ping that stacks. The reward scales directly with how good that one button is, which pushes the card toward decks built around a single keystone activation rather than toward generic value shells. Haste is the underrated clause. Most of the creatures worth targeting are exactly the ones you least want to leave summoning-sick for a full rotation, and attaching the bracers lets them act the turn they arrive, before the table gets a window to remove the engine. Put together, it is a piece for the player who assembles a board around one keystone creature and wants to press its button twice on the turn it matters, asking only a generic equip cost and a spare generic mana per copy to do it.
