Hammerhand

Strip the haste and the buff and what's left is the part that actually wins the race: a one-mana enabler that pulls a blocker out of the lane the turn you swing. The package reads like three small upsides stacked on one Aura, but the design is really a single attack-step trick wearing permanent clothing. Haste matters most on the creature you cast and enchant in the same turn, turning a fresh body into an immediate attacker; the +1/+1 nudges a profitable block into a fatal one; the can't-block clause clears a defender for everything else swinging. The catch is the catch on every combat Aura: it commits a card to a single creature, so a removal spell in response to the trigger eats two of yours for one of theirs, and even when the body survives it keeps the buff but loses the tempo that justified spending the card. That fragility is why effects like this live and die by speed, not value. It belongs to the lineage of red's "make my guy bigger and shove him through" tools, the ones that turn a stalled board into lethal by addressing the math (haste for the count, +1/+1 for the threshold) and the geometry (one fewer blocker) at once. Sober as a rate, lethal as a finisher: the whole thing only makes sense the turn you are already trying to end the game.
