Card Rulings:Attack Reflector Unit

• You can Tribute a face-down “"Cyber Dragon" to activate "Attack Reflector Unit".

Mentions in Other Rulings

• Cyber Barrier Dragon: If you activate "Attack Reflector Unit" to Tribute a monster and Summon "Cyber Barrier Dragon" during the Battle Step, a replay occurs. If your opponent continues to attack with the same monster, the attack has already been declared, so the effect of "Cyber Barrier Dragon" will not stop it. However, if your opponent attacks again after that, or chooses to attack with a different monster, "Cyber Barrier Dragon" will use its effect to negate that attack.

• Proto-Cyber Dragon: If "Skill Drain" is active, this card is no longer treated as "Cyber Dragon". You could not use it for "Attack Reflector Unit", etc.
