Capashen Standard

Every cheap Aura carries the same liability: the moment your creature dies, you are down two cards for nothing, the buff and the body both rotting in the graveyard. The sacrifice line is the cure for that math. When the enchanted creature is about to die, or the +1/+1 has done its work, you cash the Aura in for a fresh card rather than letting it stick to a corpse, which means the worst case is recouping a draw instead of eating a two-for-one. That single clause hands a marginal pump effect a remarkably high floor: it almost never feels wasted, because you either ride the bump to a useful end or convert the enchantment into a replacement. The instinct behind it is the cantrip-on-a-stick logic that white and blue commons would chase for years afterward, the idea that a small permanent should ship with an exit ramp so it never becomes a dead draw. Spending two generic mana to fire the sacrifice keeps it honest as a deliberate release valve rather than a free combat trick, so the card rewards patience: hold it on a creature that matters, and when the board state shifts, the standard comes down and a new card takes its place.
