Stitcher's Graft

The +3/+3 is bait. The interesting design move is the third clause: unequip this from a creature and you sacrifice that creature outright, which turns what looks like a power boost into a contract you cannot cleanly walk away from. Most Equipment treats moving the gear around as the whole point; this one punishes you for it. That single restriction recolors every interaction the card has. You cannot re-equip it to a fresher body without killing the old one, so the bonus is locked to whatever first picked it up. The attack clause makes that body a tapped liability on the crackback, and the sacrifice clause means you cannot answer a removal spell on the Equipment by saving the creature: when the Graft comes off, the creature goes with it. The upside surfaces when you want a permanent to die. Pay the equip cost to move it onto a second creature, and the first one dies on cue, feeding any death trigger, any sacrifice payoff, any "when this creature dies" engine you have set up. At that point the no-untap drawback and the stat boost are simply the cost of admission for a sacrifice outlet that asks for two mana and a fresh target. It reads as a beefy aggressive tool and functions as a way to control the exact moment your own creature leaves the battlefield, wearing an Equipment's clothes.
