Seize the Spoils

Card advantage in red usually comes wrapped in a penalty: exile it end of turn, deal yourself damage, discard your hand. The discipline here is looting instead of raw drawing. You pay a card out of your hand as an additional cost, then replace it and one more, so the net is a two-for-two with selection rather than a pure two-for-one. That framing matters because red is supposed to be the color that struggles to refill, and the discard cost is precisely what keeps this from becoming a blue-tier engine. The Treasure token is the second half of the design, and it does more than smooth mana: it converts a card you no longer wanted into stored energy you can cash later, which means the spell often nets closer to card-neutral while advancing your board or ramping into a bigger turn. That combination (discard fodder becomes a fixed mana rock, and your hand refills to churn through the deck) is what makes it read as a fair effect that plays like an unfair one in the right shell, particularly graveyard and sacrifice strategies that want cards in the bin anyway and a floating artifact to feed. The design bolts red draw to a cost, an old instinct; the Treasure attachment is the newer one, giving the color access to selection and fixing at once and letting the discard clause carry the balance.
