Menace (This creature can't be blocked except by two or more creatures.) At the beginning of your upkeep, you may create a Treasure token (A Treasure is an artifact with ", Sacrifice this artifact: Add one mana of any color."). When you do, target opponent creates a tapped Treasure token (A Treasure is an artifact with ", Sacrifice this artifact: Add one mana of any color."). Whenever Generous Plunderer attacks, it deals damage to defending player equal to the number of artifacts they control.
