Rummaging

Hand-filtering effects where discarding is paid as a cost and drawing follows as the payoff, churning unwanted cards in hand into fresh ones. Cathartic Reunion pitches two for three, Thrill of Possibility trades one for two at instant speed, Big Score and Seize the Spoils tack Treasures onto the swap, and Rummaging Goblin grinds the loop on a creature body. Distinct from card_advantage.looting, where you draw first and then choose what to discard with full information; here the discard is locked in before you see the new cards, which matters for graveyard-fueled decks that want to bin specific pieces. Also distinct from card_advantage.wheel, which resets entire hands rather than swapping a few cards.
