Repeatable, unblockable life loss that charges its rent in bodies. The Cohort activation asks for two Allies at once: this card's own tap plus the tap of a second untapped Ally you already control. That double cost is the entire balancing act. The 4/2 body is fragile enough that it will not always survive to be tapped, and the ability sits inert without a board wide enough to spare a second creature without gutting the attack. Once the engine turns on, the effect recurs each turn and ignores blockers entirely, converting a go-wide Ally board into a clock the red zone cannot answer. But every activation costs presence on the battlefield, so the card forces a standing choice between pressing the swing and grinding two life at a time. That self-limiting cost marks it as the attrition-minded half of the Ally plan: the piece that turns a stalled board into inevitability rather than one that wins a race. It rewards full commitment to the tribe and nothing less; short of a critical mass of Allies, it is a 4/2 with text it can never switch on.
