Rulings
- Exodia Necross cannot be Normal Summoned or Set, and cannot be Special Summoned EXCEPT by the effect of Contract with Exodia. So Exodia Necross cannot be Special Summoned with Monster Reborn, etc., even if Special Summoned properly first.
- Players can activate Spell & Trap Card effects that destroy monsters, but Exodia Necross will not be destroyed by them.
- If a piece of Exodia is removed from the GY while Exodia Necross is removed from play due to Dimensionhole, Exodia Necross is destroyed when it returns to the field.
- If your opponent takes control of your Exodia Necross and does not have all 5 pieces of Exodia in his/her GY, Exodia Necross is destroyed if face-up.
- While Skill Drain is active, Exodia Necross' ATK is returned to its original 1800 points. Even if Skill Drain then leaves play, Exodia Necross does no regain any ATK increases it had because of its effect, but it will begin to accumulate ATK points again.
- While Skill Drain is active, Exodia Necross is not destroyed if Exodia pieces are removed from the GY, but it will be destroyed if the effect of Skill Drain disappears.
