Powerstone Engineer

Most death triggers pay you at the moment of the trade: a card, a body, a drained life point, cashed the instant the creature falls. This one defers the reward by a full turn. The corpse leaves behind a Powerstone, and because that token arrives tapped, there is no cheating a turn out of it; the acceleration only ticks online later, once the creature that funded it is already gone. That gap between death and payoff is the design point, and it reroutes where white usually places value on a cheap creature. White's typical two-drop death triggers lean toward lifegain or a replacement body, keeping value inside the color. Here the reward is colorless mana that steers toward artifacts rather than into anything you could splash, which reads less like a white weenie and more like sacrifice fuel wearing white's clothing. The body is happy to trade into whatever it meets, because losing it is when the card finally earns its keep: a chump-blocker whose remains bankroll the next construct or activation. Small creature, small payoff, but the shape of that payoff (colorless, delayed, funneled) tells you precisely which deck it was built to feed and which decks should leave it alone.
