The upkeep timing is the whole knot here. Most sacrifice-as-reach payoffs fire the moment you feed them fodder, rewarding you for jamming everything the turn you draw the outlet. This one insists on a delay: you decide at the start of your turn, before you draw, before you attack, whether a creature is worth two points to the face. That constraint pushes the card away from burst combos and toward attrition play, where a board is slowly converted into damage a creature at a time. Aristocrats shells want exactly this cadence, because the sacrifice pays out twice over: it fires two damage at the opponent and it triggers whatever else cares about a creature dying. The haste is a quieter piece of the same idea; a two-power body ready to attack the turn it enters gives you a reason to keep the creature on offense rather than treating the sacrifice engine as the only thing it exists for. The damage reaching only an opponent or planeswalker, never a creature, is what keeps it a reach tool rather than a removal engine, and separates it from other sacrifice-for-value creatures that can also clear a blocker. Its ceiling is inevitability: a mana-free clock that ticks once per turn for as long as you can keep bodies coming.
