Outpace Oblivion

Five damage to a creature or planeswalker for is a rate aggressive enough to justify the card on the enter-the-battlefield burn alone, and the sacrifice mode grafts a second win condition onto that clean removal: two to every player who hasn't reached max speed. That clause is where the speed track stops being decoration and starts doing work. The speed counter climbs only during your turns, and only once each turn, and only after an opponent loses life directly, so the enchantment quietly builds toward its own exemption while measuring everyone else against the same clock. The important subtlety is that the initial burn cannot feed that counter at all: it targets creatures or planeswalkers, never players, so it does no work toward the speed condition. The increments have to come from elsewhere, from attacks, from a reach spell, from anything that touches a life total. That gap between what the card kills and what advances its speed is the whole puzzle. The payoff wants a deck already chipping at life turn after turn, and it rewards the deck winning the race by handing it a one-sided finisher pointed at whoever tried to sit still and durdle. The card does not create the race; it collects on it.
