Leech Gauntlet

Reconfigure was built to solve the oldest problem Equipment has: the dead draw. Traditional Equipment sits in your hand doing nothing until you have a creature to hold it, and sits on the battlefield doing nothing after that creature dies. This one hedges both ways. Drawn early with no board, it is a 2/2 that swings and gains life on its own; drawn late with a threat already deployed, four mana staples the lifelink onto something bigger and the Equipment stops being a creature (dodging removal that targets creatures, ducking under sweepers that count bodies). The keyword collapses the old choice between "a creature that helps" and "a permanent that upgrades a creature" into a single card that is whichever one you need this turn. The rate is modest and the ability it grants is the plainest one in the game, which makes it the most legible reading of Reconfigure available: nothing about the effect distracts from what the keyword is doing, so the mechanic teaches itself. The Leech creature type is flavor doing quiet work, a bloodsucker that literally attaches to feed. What makes the design durable is that the flexibility costs almost nothing on the front end; you pay only when you decide to move the lifelink, and until then you have a body that was never a wasted slot.
