Prosper turns every end step into extra card advantage by exiling a card, and every card played from exile into a Treasure. The deck stacks more exile-play sources (impulse draw, cascade, stealing from opponents' libraries) to multiply those triggers. The resulting stream of Treasures fuels big plays, while artifact-death and sacrifice payoffs convert each Treasure cracked into chip damage against opponents. Passionate Archaeologist on Prosper and spell copiers like Nalfeshnee turn casting from exile itself into a damage engine. How it wins: Playing card after card from exile generates and sacrifices piles of Treasure, so Prosper's Background triggers, Alchemist's Talent, and the aristocrat-style drain pieces bleed the table out, backed by Treasure-scaling threats like Smaug and Goldspan Dragon. Key roles: - Impulse draw from own library: Exiles extra cards from the top of the library to play, giving card advantage while firing Prosper's Treasure trigger on each card played (Light Up the Stage, Outpost Siege, Commune with Lava) - Playing opponents' cards: Exiles or steals cards from opponents' libraries, graveyards or battlefields and casts them, which also counts as playing from exile for Prosper (Laughing Jasper Flint, Gonti, Lord of Luxury, Hurl Through Hell) - Cascade and free-spell chains: Cascade and free-cast effects turn one spell into several, and each cascaded spell is cast from exile, so it adds more Treasures and copy or damage triggers (Wild-Magic Sorcerer, Rain of Riches, Improvisation Capstone) - Cast-from-exile payoffs: Turn each spell cast from exile into direct damage or a copied spell, making Prosper's engine lethal on its own (Passionate Archaeologist, Nalfeshnee, Alchemist's Talent) - Treasure aristocrats: Each Treasure that is sacrificed, enters, or is created drains or pings opponents, so the mana Prosper makes doubles as reach (Disciple of the Vault, Marionette Apprentice, Mayhem Devil) - Treasure scaling threats: Creatures and spells that mass-produce Treasures or grow stronger with them, turning the Treasure pile into big mana and evasive finishers (Smaug the Magnificent, Goldspan Dragon, Brass's Bounty)
