If you have 5 or more Dragon Synchro Monsters with different names in your GY: Special Summon 1 "Stardust Dragon" from your Extra Deck (this is treated as a Synchro Summon), and equip it with this card, but banish it during the End Phase. That equipped monster gains ATK equal to the combined ATK of all Dragon Synchro Monsters in your GY. Each time that equipped monster destroys an opponent's monster by battle: You can banish 1 Dragon Synchro Monster from your GY; that equipped monster can attack an opponent's monster again in a row.
