Devouring Hellion

The doubling is where the design actually lives. Most sacrifice-payload creatures pay you back at parity: throw three bodies at it and get three counters, a wash you could have gotten by attacking with the bodies themselves. This one pays two-for-one on the fodder, turning a fistful of expendable tokens into a single body whose size scales faster than the count you feed it. Sacrifice four small creatures and a 2/2 arrives as a 10/10, which reframes the whole calculation: you are converting a wide board into one oversized threat as it enters. That conversion is the point, and it is also the risk, because everything you fed it now rides on one permanent. Spot removal answers the whole board at once; sacrifice four bodies into it, eat a kill spell after it resolves, and you have handed the opponent a five-for-one. The counters being permanent is what makes the gamble worth taking: the payoff sticks rather than fading like a temporary pump, so a hexproof enabler or an unanswered swing closes games in a hurry. The catch is baked into the timing. The sacrifice is a replacement effect that fires only as the creature enters, a one-shot conversion with no way to feed it again later, so the fodder has to be committed on the turn it lands rather than held in reserve. It is a finisher for a board already gone wide, not a value engine you deploy early and grow over time.
