Frenzied Raider

Every boast ability that fires anywhere on your side stacks a counter here, which turns a dispersed, once-per-turn mechanic into a single accumulating threat. That is the design idea: boast tends to fight itself, since each attack unlocks an activated ability but the payoffs are modest and rarely justify committing creatures to the red zone. This two-mana 2/2 collects those small commitments and compounds them. What keeps it from spiraling is boast's own tax structure. Each ability is limited to once per turn per creature and demands an attack to unlock it, so the counters arrive at the pace of your combat commitments, not your mana. Deploy a wide board of aggressive boasters, keep swinging, and the returns pile onto one Demon Berserker that outgrows the removal aimed at the rest of the team. Left alone across a few turns of attacks, that unassuming body becomes the clock the boast plan otherwise struggles to assemble, which is the whole point: it is both the mechanic's engine and its finisher folded into one slot.
