Card Rulings:Archfiend Zombie-Skull

TCG Rulings

• If monsters are being treated as Zombies by “DNA Surgery” and you attempt to Summon a 2^nd copy of “Gravekeeper’s Chief” while you already control one, it will be destroyed because this is not considered to be a card effect.

• If you control “Archfiend Zombie-Skull” and “Il Blud” and “Il Blud” is removed from the field ^[sic], any monsters Summoned by the effect of “Il Blud” will not be destroyed.

OCG Rulings

• If "Archfiend Zombie-Skull" is on the field, monsters Special Summoned by "Il Blud" are not destroyed when "Il Blud" is removed from the field. This includes if "Archfiend Zombie-Skull" is itself Special Summoned by the effect of "Il Blud".

• When a monster like "Gravekeeper's Chief" is destroyed because you can only control one copy of "Gravekeeper's Chief", it is not treated as being destroyed by a card effect. When "Archfiend Zombie-Skull" and "DNA Surgery" declaring "Zombie" are on the field, if a second "Gravekeeper's Chief" is flipped face-up, then it will still be destroyed.

• If "Zombie World" or "DNA Surgery", ect, is face-up on the field and makes all monsters on the field Zombie-Type, and the effect of "Archfiend Zombie-Skull" is applied that prevents the Zombie-Type monsters from being destroyed by card effects, then when "Black Rose Dragon" is Synchro Summoned and its effect that destroys all cards on the field is activated, even though "Archfiend Zombie-Skull" and "Zombie World" would be destroyed simultaneously ^[sic], "Black Rose Dragon" still treated as a Zombie-Type, so it is not destroyed by the effect and remains to the field.
