Spare Dagger

Equipment that eats itself is a small but pointed design idea: rather than a permanent buff sitting on the board, this trades its own existence for a single point of reach at the moment the equipped creature swings. The +1/+0 is the passive rate, the thing it does while attached, but the real payload is the attack trigger. Because the sacrifice fires during the Declare Attackers step, the timing is committal: you feed the dagger to the graveyard when the attack trigger resolves, then point one damage anywhere before blockers are even declared. That is reach for a mana dork, a planeswalker loyalty tax, or the face, not a post-combat cleanup on a blocker. The repayable equip cost matters too, because until you pull the trigger the dagger is reusable, hopping from body to body and threatening the sacrifice each combat until you like the target. The tension it resolves is the one every cheap Equipment faces: how do you make a marginal stat boost worth a card and an activation? The answer here is to fold a disposable damage source into the package, so the dagger holds its threat in reserve rather than sitting as dead weight. It reads as filler and plays as a slow drip of artifact-death triggers and incidental reach for anything that cares about equipment entering, leaving, or dying.
