Gauntlets of Light

Two changes to combat math, layered on the same defensive body. First, the toughness bump: +0/+2 keeps the creature alive through more of what would otherwise trade with it. Then the swap that makes the Aura worth casting: the enchanted creature deals damage equal to its toughness instead of its power, so every point of defense doubles as offense. Stack it on a creature whose toughness already outstrips its power (a wall, a fat-butted defender, anything with a lopsided stat line) and you turn a blocker into a threat without touching the top number. The untap ability is the piece that closes the loop: for you can ready the creature after it attacks, so a high-toughness body can swing and still stand up as a wall on the crackback. That is the design logic behind the whole card: it wants a creature that was never built to attack, and it rewrites both halves of the combat equation to send it in anyway. The friction is real (three mana on an Aura is card disadvantage waiting to be two-for-one'd, and the untap costs enough that repeated use is a mana sink), but the payoff is a strategic inversion that most defensive creatures never get to enjoy: the stat you were hiding behind becomes the stat that kills.
