Overstocked

Bargain (You may sacrifice an artifact, enchantment,
or token as you cast this spell.)
When Overstocked enters the battlefield, target
opponent gains control of it and another artifact, enchantment, or token you control. If this spell was bargained, each opponent creates a copy of
Overstocked.

At the beginning of your upkeep, Overstocked deals
3 damage to you. Overstocked's owner creates a
Treasure token.
