Rulings
- When a card that selects a card in the GY as a target, such as Monster Reborn, Mask of Darkness, Magician of Faith, Spear Cretin, or The Shallow Grave, is activated, you may chain Disappear to remove the targeted card from play, and the Monster Reborn, etc., will resolve without effect. This is because these cards select their target at activation, not resolution.
- Bazoo the Soul Eater removes a monster in the GY as a cost, so you cannot chain Disappear to the effect of Bazoo the Soul Eater to negate it. The monster is already removed from play before you can activate Disappear.
- If you chain Disappear to your opponent’s Backup Soldier you can remove one of the targeted monsters from play, but the remaining two (or less) go to the opponent’s hand.
