TCG Rulings

Mentions in Other Rulings

• Crimson Fire: If you control “Red Dragon Archfiend/Assault Mode” but not “Red Dragon Archfiend,” you cannot activate “Crimson Fire.”

• Majestic Red Dragon: The effect that activates during the End Phase targets 1 "Red Dragon Archfiend" in your Graveyard.

• Red Dragon Archfiend/Assault Mode: The last effect targets the “Red Dragon Archfiend” in the Graveyard.

Judge Program Forum Rulings

• XX-Saber Emmersblade: The effect of "XX-Saber Emmersblade" does not activate during Damage Calculation. It activates when cards are sent to the Graveyard in the Damage Step. So, if "Red Dragon Archfiend" attacks a Defense Position "XX-Saber Emmersblade", the effect of "Red Dragon Archfiend" will activate and resolve before "XX-Saber Emmersblade" activates. Since "XX-Saber Emmersblade" was destroyed by the effect of "Red Dragon Archfiend" and not by battle, its will not activate.

OCG Rulings

• "Red Dragon Archfiend" is treated as an "Archfiend" monster.

• The "After damage calculation, if this card attacks a Defense Position monster your opponent controls: Destroy all Defense Position monsters your opponent controls." effect is a Trigger Effect. (It does not target.)

• The "During your End Phase: Destroy all other monsters you control that did not declare an attack this turn." effect is a Trigger Effect. (It does not target.)

• Even if all monsters you control attacked this turn, this effect still activates during the End Phase.

Q&A Rulings

• Q: "Red Dragon Archfiend" and "Red Sprinter" are face-up in my Monster Zone, in Attack Position. If my "Red Sprinter" attacks, but the attack is negated by the effect of my opponent's "Magic Cylinder", will "Red Sprinter" be destroyed by the effect of "Red Dragon Archfiend" during the End Phase?

A: In this scenario, the attack by "Red Sprinter" was negated by the effect of "Magic Cylinder", but since an attack was declared, it is not a monster on your field that did not declare an attack. In this case, the effect of "Red Dragon Archfiend" will activate during the End Phase, but "Red Sprinter" is not destroyed.

• Q: When "Red Dragon Archfiend" destroys a Defense Position monster by battle, is the monster treated as being destroyed by battle?

A: When "Red Dragon Archfiend" attacks and destroys a Defense Position "Giant Rat", the effect of "Red Dragon Archfiend" destroys "Giant Rat", so the effect of "Giant Rat" is not activated.

Previously Official Rulings

• "Red Dragon Archfiend's" effect activates after damage calculation in the Damage Step, before the effects of flipped Flip Effect Monsters or the effects of cards like "D.D. Warrior" activate. If "Red Dragon Archfiend" attacks a face-down Flip Effect monster and destroys the Flip Effect monster with its effect, the Flip Effect monster's Flip Effect activates after it is destroyed.

• If the Defense Position monster attacked by "Red Dragon Archfiend" is changed to Attack Position before damage calculation with "Final Attack Orders", etc., "Red Dragon Archfiend's" effect does not activate.

• If "Red Dragon Archfiend" attacks a Defense Position "Giant Rat," etc., and destroys it with its effect, "Giant Rat's" effect does not activate because it is destroyed by "Red Dragon Archfiend's" effect before it would be sent to the Graveyard by battle.

• If the attack of one of your monsters is negated, with "Magic Cylinder", etc., the monster is destroyed by "Red Dragon Archfiend's" effect in your End Phase.

• “Red Dragon Archfiend’s” second effect will activate during each of your End Phases, even if every monster you control has attacked.
