Rulings
- This card should say FLIP: Both players can remove from play up to 3 cards from their opponent's GY., not up to 3 monsters.
- You can use Dimension Jar's effect for zero to three cards, so even if your opponent has less than 3 cards in his GY you can still use Dimension Jar's effect.
- When Kycoo the Ghost Destroyer is on the field and Dimension Jar is activated, the controller of Kycoo the Ghost Destroyer can remove their opponent's cards in the GY from play.
