My Wealth Will Bury You is a common Scheme card from Duskmourn: House of Horror Commander (DSC), collector number 346. Current market price: $0.28, TCGplayer market prices via Scryfall.
When you set this scheme in motion, create a number of Treasure tokens equal to the number of artifacts and enchantments your opponents control. If they control fewer than four artifacts and enchantments, create four Treasure tokens instead. (Treasure tokens are artifacts with "{T}, Sacrifice this token: Add one mana of any color.")
