Impulsive Pilferer
A one-red goblin whose value accrues entirely after death. The first payout comes when it dies: chump it, trade it, or feed it to an outlet, and it leaves behind a Treasure that ramps or fixes on the very turn it goes. Encore is the second payout, and it runs on a longer fuse. For 
you exile it from the graveyard to mint a hasted token copy aimed at each opponent, all of them forced into the red zone, all of them dying that end step to cough up still more Treasures. That per-head multiplier is what marries the design to a full table: the same activation makes a lone raider against one rival and a three-deep raiding party against three, and every dying copy loops back into mana. Because encore exiles the card as part of its cost, the second payout can only fire once; there is no rebuilt loop here, only a deferred alpha strike you cash when the token spread and the Treasure yield line up. The 1/1 body barely enters the arithmetic beyond being a legal attacker and something cheap to discard. Everything worth counting happens in the afterlife: it pays when it dies, then pays again when it leaves the graveyard, and the original goblin was never really the asset.
