Goldmaw Champion

Attack first, then tap. That sequencing is the whole trick of this Dwarf's design: the tap ability looks like a defensive tool, but you can only fire it after the creature has already swung, so it never folds back into your blocking assignments. It clears the way for its own assault instead. Send it in, pay , tap the biggest thing that would have blocked, and keep the ground pressure on. The once-per-turn cap keeps it from spiraling, and because the whole boast structure commits you during your own combat rather than reacting during theirs, the untapped creatures you get to neutralize are the ones sitting in the way of your swing. The 2/3 body for is unremarkable, and that is deliberate: the stat line is a delivery vehicle for a repeatable effect that only ever rewards the aggressor. Where instant-speed tappers like Master Decoy let you hold up mana and pick off a blocker at any point, this one charges a turn of forward commitment up front and bolts the tapper onto an attacking game plan. It is an efficient expression of the mechanic's central bargain: put the ability behind the attack step and you get a repeatable tool that punishes anyone trying to stabilize on the ground.
