Brokers Confluence

The Confluence template's structural gimmick is that repetition is free: choose three modes, and nothing stops you from stacking the same one twice or three times. That mechanic finds its sharpest expression here, because two of these three modes want to be doubled. Proliferate scales with itself in a way most modal spells never get to; one proliferate on a board of planeswalkers, +1/+1 counters, and poison advances every counter one tick, and three copies advance every counter three ticks in a single instant. The phase-out mode is the wrinkle that pushes this past a pure counter-doubling engine: it treats a creature and its attachments as though they don't exist until its controller's next turn, which is a fog for one attacker, a save from a board wipe, or a way to strand an aura or equipment for a turn, all at instant speed and none of it destruction the way removal is destruction. The third mode, countering an activated or triggered ability, is the interactive tax that keeps the spell from being pure engine fuel: it answers the ETB trigger, the sacrifice payoff, the tutor activation. The color identity is what makes the grab bag cohere. Bant is the shard that most naturally hosts counters, blink, and control elements at once, so a single card that proliferates, protects, and answers reads less like a menu and more like a mission statement for the three colors it costs.
