Based on Ringu with a splash of Garth One-Eye. I love the concept of reprinting cards within cards.
SadakoWB
Legendary Artifact Creature - Spirit
Menace
When Sadako 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 Sadako from your graveyard to your hand.

1/1
The play pattern is cool though.
