Hidden Footblade

Most equipment is a two-turn proposition: cast it at sorcery speed, then pay again to attach before a creature is any bigger. This one collapses both halves into a single instant-speed play. Cast it in response to blocks and its enter trigger attaches for free, handing the equipped creature first strike until end of turn, which turns a favorable block into a one-sided kill or ambushes an attacker with a suddenly-lethal combat step. The permanent buff underneath is modest by design: +1/+0 and haste is a rate that wants to move from creature to creature rather than anchor to one, and the equip cost is high enough to discourage rebuying it every turn. The value is front-loaded into the flash entry, not the equip line. What that produces is a combat trick that leaves a permanent behind. Unlike a burned-through instant, the +1/+0 and haste persist, so a creature you saved at instant speed keeps the bonus, and the next creature down can inherit it later for the equip fee. It reads the combat step the way a pump spell does while sticking around as the artifact it is: a small, precise piece of red aggression that rewards holding priority over committing on your own turn.
