Rulings
- The first sentence of this card’s text means that monsters such as Beastking of the Swamps cannot be used as a substitute for one of the required Fusion Material Monsters. You CAN use the effect of Magical Scientist or Summoner of Illusions to Special Summon this card like any other Fusion Monster.
- You can only use this card’s effect to negate Normal Spell Cards, not Quick-Play, Equip, Continuous, Field, or Ritual Spell Cards. This effect is a Multi-Trigger Effect, so it is Spell Speed 2 and may be activated during the opponent’s turn.
- This card’s effect only negates the effect of a Spell Card when it is activated, not the activation. So if your opponent activates Swords of Revealing Light and you activate the effect of this card to negate it, it will remain meaninglessly on the field for 3 turns. Its effect will remain negated for all 3 turns even if Dark Balter the Terrible is later destroyed.
- This card’s effect to negate the effect of Effect Monsters that it destroys as a result of battle is a separate effect from the other one; you do not pay LP to activate it. This effect works the same as the effect of Dark Ruler Ha Des; see that card’s rulings for more details.
- "Dark Balter the Terrible" must destroy a monster to negate that monster’s effect.
- Monsters that were destroyed by "Dark Balter the Terrible" and leave the GY will no longer have their effects negated.
- "Dark Balter the Terrible" does not negate Special Summoning restrictions from the GY, including those of "Tyrant Dragon," "Dark Ruler Ha Des," and "Helpoemer." If "Dark Balter the Terrible" destroys a Flip-Effect monster, the Flip-Effect monster’s effect is negated.
- If "Dark Balter the Terrible" destroys "Marie the Fallen One" in battle, "Marie the Fallen One’s" GY effect of ‘increase the players LP by 200 each SP’ is negated.
- If "Dark Balter the Terrible" attacks a face up attack position "Refl ect Bounder", "Refl ect Bounder’s" effect of inflicting Damage equal to the ATK of the attacking monster will not be negated. If "Dark Balter the Terrible" destroys "Reflect Bounder," "Reflect Bounder" will be considered destroyed as a result of Battle and not as a result of "Reflect Bounder’s" effect.
