Pitiless Horde

A 5/3 for three mana is already past the curve red and black aggro decks of its era usually drew the line at, and the upkeep life-loss is the bill that comes due for it. The two life every turn is not a downside in the way a creeping drain on a control deck would be; it is a clock pointed at the controller. This is a card built to attack and die before its own tax matters, which is exactly what the dash cost reframes. Cast it from hand and you own a fast clock that quietly bleeds you out if the game stalls. Cast it for dash and you sidestep the upkeep trigger entirely: the Horde swings for five with haste, bounces to your hand at end of step, and the life-loss clause never sees an upkeep to fire on. The recurring-haste plan turns a self-destructive body into a repeatable burst of damage, paying extra mana each turn to dodge the very drawback that defines the permanent version. That tension (a body too good to leave on the table, attached to a cost that punishes leaving it there) is the whole design, and dash is the release valve that lets an aggressive deck have the stats without eating the attrition. Built for the deck that wants to be empty-handed by turn five and does not expect to be alive on turn ten.
