Tavern Brawler

Most Backgrounds hand your legend a static keyword or a cast-trigger and step aside; this one bolts a slow, recurring impulse engine onto whatever leads your deck, keyed to a very specific scope: commander creatures you own, not any old legend in the 99. Each of those creatures reads its own upkeep trigger, exiling the top card, swinging bigger by that card's mana value, and daring you to actually play it before the turn ends (paying its cost in full) or lose the card back to exile. That the boost is +X/+0 rather than a counter or an evergreen keyword is the tell that it was drawn for red aggression, not slow value: even a whiff usually leaves a fatter attacker in the red zone, and the pump scales with whatever mana value you turn up. It also dictates the curve, rewarding a library that stays castable off the top rather than a pile of expensive finishers that each surface only to strand themselves in exile. The clause that lifts it above a solo pilot's toy is the plural: a partner pair stacks a separate triggered ability per body, and because those triggers resolve independently, each exiles a different card rather than fighting over the same one. Among the aggressive jobs the Background frame has been asked to shoulder, this one commits fully to red beatdown instead of drifting toward generic goodstuff value.
