Widespread Brutality
The old red-black fantasy is a wrath that leaves one creature standing, and the twist here is that the survivor is the very engine that did the killing. Amass Zombies 2 builds a 2/2 Army, and that Army's power is what gets swept across the board: damage to every non-Army creature, with the Army itself untouched because the effect spares Armies, not Zombies. That distinction cuts deeper than it reads. This is an Amass payoff, not a Zombie payoff: any real Zombies you control that are not the Army get burned along with everything else. The number is not fixed, either. Start with a bare board and you clip tokens, mana dorks, and one-drops for two; walk in with a pre-existing Army already fed by earlier amass triggers, and the sweep scales up to that Army's power, potentially clearing far more than the floor suggests. The design lives in the tension between removal and development: most sweepers cost you the board and a turn spent rebuilding, while this one hands you a growing threat on the way out and rewards a deck that keeps stacking counters on a single Army. The compounding is the whole appeal: the more Army-fueling cards you run, the harder each successive cast lands, until the sweep and the threat you keep are literally the same permanent.
