Jump Scare

In Commander, Jump Scare earns its slot in token, enchantment-matters, and copy-spell shells — two mana for a 4/4 with trample at instant speed is above rate, and the enchantment token it leaves behind feeds Yenna, Redtooth Regent and similar payoffs. In competitive 1v1 formats like Modern and Pioneer, a 4/4 for two is tempting but the body enters as a sorcery-speed-equivalent on your turn most of the time, and dedicated token or flash strategies have tighter options. Pauper is where Jump Scare gets the hardest look outside Commander, since efficient instant-speed threats are scarce at common, though the lack of tribal or enchantment synergies at that power level limits it. Legacy and Vintage have no interest — the bar for two-mana spells is simply too high.
