This is a Rakdos Treasure deck that turns Treasure into a value and damage engine. Smaug, Wicked Worm draws a card whenever Treasure mana pays for a spell, and Mastermind Plum duplicates that draw. A large suite of Treasure makers fills the board: combat-damage triggers on dragons and creatures, upkeep generators, and rituals and card draw that leave Treasures behind. Multipliers grow every batch, and each Treasure entering or being sacrificed is converted into direct damage and life drain against the table. How it wins: The deck drains opponents to death through enter and sacrifice triggers on its artifacts and Treasures and hits with evasive dragons, with backup alternate wins from controlling ten or more Treasures, twenty artifacts, or thirty artifacts at upkeep. Key roles: - Treasure-cast card advantage: Spells paid for with Treasure mana draw cards through Smaug, Wicked Worm and its twin, and later deal damage equal to the spell's mana value or cascade into free spells, so the Treasure pile becomes card and tempo advantage. (Mastermind Plum, Alchemist's Talent, Rain of Riches) - Combat Treasure generation: Evasive, hasty or double-striking attackers and combat payoffs create Treasures whenever damage connects. Some scale with the opponent's artifact count, and Smaug the Magnificent turns the stockpile into attack-trigger damage. (Goldspan Dragon, Ancient Copper Dragon, Smaug the Magnificent) - Treasure multipliers and untappers: These make each Treasure-making effect produce more. They add extra Treasures, add Clues and Food alongside them, double Treasure mana, and untap the tapped Treasures from Smaug, Wicked Worm's own entry trigger. (Xorn, Academy Manufactor, Amulet of Vigor) - Artifact-enter and sacrifice drain: Pingers punish every artifact entering and every token being created, sacrificed or leaving play. Mass Treasure creation and spending becomes repeated damage to each opponent. (Ingenious Artillerist, Mayhem Devil, Mirkwood Bats) - Opponent-artifact exploitation: Some cards give opponents Treasures or count their artifacts. This fuels Smaug, Wicked Worm's entry trigger, the deck's cost reducers and its burst mana, and also sets up stealing their artifacts outright. (Descent into Avernus, Dragon's Desire, Hellkite Tyrant) - Alternate win conditions: Big Treasure and artifact counts are threats on their own, since these cards win the game at upkeep once the stockpile is large enough. Sacrifice outlets and tutors convert surplus Treasures into finding them. (Revel in Riches, Knuckles the Echidna, Magda, Brazen Outlaw)
