Send 1 "Galaxy" monster from your hand and 1 from your Deck to the Graveyard. Then, you can use one of the following effects once per turn. Each effect can be used once per Duel: ● Add 1 "Neo Galaxy-Eyes Photon Dragon" from outside of your Deck to your Extra Deck. ● If you Xyz Summon "Neo Galaxy-Eyes Photon Dragon" this turn, you can also Xyz Summon it by using "Galaxy-Eyes Photon Dragon" you control as the material, one time only. This Skill can be used if you begin the Duel with a Deck (excluding Extra Deck) that contains at least 10 "Galaxy" cards and no monsters other than "Photon" or "Galaxy" monsters.
