Araumi of the Dead Tide

Encore is normally a graveyard cost stapled to a single creature card, spent once and gone; this Merfolk relocates the mechanic from the card to the caster and makes it a repeatable engine. The tap ability doesn't just recur one creature, it hands encore to any creature in the yard turn after turn, which turns the graveyard into a rolling armory of enters-the-battlefield and dies triggers you can fire off in copies scaled to the number of opponents at the table. The fuel cost is the counterweight: each activation exiles cards from your own graveyard equal to your opponent count, so the more players you're pressuring, the faster you strip the very resource you're mining. A defensive 1/4 body content to sit back, a sorcery-speed restriction on the activation, and a self-cannibalizing cost all pull against the ceiling of an ability that could otherwise generate absurd token volume. What it really rewards is a deck built to keep the graveyard full and to squeeze value out of one-shot copies that vanish at end of step: sacrifice fodder, death-trigger creatures, ETB value engines that don't care about being temporary. The design reads less as a payoff for casting spells and more as a payoff for filling and refilling the yard, an aristocrats-and-reanimator hybrid packaged into a single three-mana commander.
