Ariel the Bound

When Ariel the Bound enters the battlefield,
create a colorless artifact token named Jinxed
Ring with "Whenever a nontoken permanent is
put into your graveyard from the battlefield,
Jinxed Ring deals 1 damage to you," and
"Sacrifice a creature: Target opponent gains
control of Jinxed Ring."
Sacrifice Jinxed Ring: Return Ariel the Bound
from your graveyard to your hand.
