Rulings
- 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.
- While Skill Drain is applying, Berserk Dragon's effects are negated. But Berserk Dragon's effect doesn't count turns, so if Skill Drain was applying for 4 turns, and is then destroyed, do not reduce Berserk Dragon's ATK for those 4 turns.
- If "Berserk Dragon" is flipped face down, when it is turned face up again, it will have its original ATK value of 3500.
- If "Berserk Dragon" attacks LP directly, it may not attack any monsters that may later be on the field.
- Q: Can "Berserk Dragon" (or "Exodia Necross" or "Dark Paladin") be flipped facedown and then Flip Summoned? A: It is alright to Flip Summon them.
