Card Rulings:Berserk Dragon


 * "Berserk Dragon" cannot be Normal Summoned or Set, and cannot be Special Summoned EXCEPT by the effect of "A Deal with Dark Ruler". So "Berserk Dragon" cannot be Special Summoned with "Monster Reborn", etc., even if Special Summoned properly first.


 * If "Berserk Dragon" is removed from play with "Interdimensional Matter Transporter", you cannot try to resolve "Berserk Dragon"'s effect before it returns to play; you must return it to play first and then it loses 500 ATK.


 * While "Skill Drain" is active, "Berserk Dragon"'s effects are negated. But "Berserk Dragon"'s effect doesn't count turns, so if "Skill Drain" was active for 4 turns, and is then destroyed, do not reduce "Berserk Dragon"'s ATK for those 4 turns.

Mentions in other rulings

 * A Deal with Dark Ruler: You can only Special Summon 1 monster with "A Deal with Dark Ruler", but you can activate 2 copies of "A Deal with Dark Ruler" to Special Summon 1 "Berserk Dragon" for each, even if only 1 Level 8 or higher monster was sent to the Graveyard.


 * Skill Drain: When a monster's ATK or DEF are changed by its own effect, like "Slate Warrior" or "Berserk Dragon", and "Skill Drain" is activated, that monster's effect is negated and the ATK/DEF are returned to normal. Even if "Skill Drain" is then destroyed, the old adjustment to ATK/DEF does not come back. Any bonuses or penalties are lost when "Skill Drain" effect is applied, and you have to start over from the beginning.
