Burr Grafter

Sacrificing the body buys a +2/+2 pump on a single creature: an unremarkable trade on its own, a 2/2 spent to win one combat or push a few points through. The death trigger is where the math turns. When this Spirit dies (and it wants to die), Soulshift 3 returns a cheap Spirit, mana value three or less, from the graveyard to your hand. So the sacrifice cost and the death payoff resolve in sequence: you pay the body for the pump, then collect a returned Spirit as the body leaves. The card economy never comes out clean-negative, because the act of spending it refuels the next play. That makes Burr Grafter a tail-end piece in a Spirit chain rather than a centerpiece, a disposable fuel cell that converts itself into a combat swing and a recursion trigger at once, while feeding the death triggers other Spirits in the loop care about. The deckbuilding logic is recursive by intent: each death recycles an earlier small Spirit, so the modest stats and the eager-to-sacrifice body only justify themselves inside a graveyard engine stacked with three-drops and under. Pull it out of that shell and a 2/2 for whose best use is dying has little to offer. It was engineered to live inside the chain, not beside it.
