Revel in Riches

Enchantment

Whenever a creature an opponent controls dies, create a Treasure token. (It's an artifact with ", Sacrifice this token: Add one mana of any color.")At the beginning of your upkeep, if you control ten or more Treasures, you win the game.

"I can prove I won fair and square—I have the receipt."
