Card effect (current official text)Fusion Summon 1 Dragon Fusion Monster from your Extra Deck, by banishing Fusion Materials listed on it from your field or GY.
Rulings
Remove from play, from your side of the field or your GY, Fusion Material Monsters that are listed on a Dragon-Type Fusion Monster Card, and Special Summon that Fusion Monster from your Fusion Deck. (This Special Summon is treated as a Fusion Summon.)
- "Dragon’s Mirror" does not target. You select and remove the monsters during resolution.
- If "Kycoo the Ghost Destroyer" is on your opponent’s side of the field, you can activate "Dragon’s Mirror" if all the Fusion Material Monsters are on the field; but not if any of them are in the GY.
