Just stick a single Rank 8 to win. Prime Photon detaching Afterglow gets boosted to 11200 on its own, so you can OTK over anything with 3200 or less.
Photon Sanctuary is basically RotA, it makes Union Carrier to equip Orbital which searches your entire deck. Usually you'll search Galaxy Soldier then with that search Galaxy Knight, but you might search either of your big dragons too. It's also non-OPT, so multiples let you summon your other links for free.
Galaxy Trance is amazing for pushing through interruption. As long as you have Photon Dragon in grave, it summons it and then Afterglow from deck. NOTE: You're locked out of the Union Carrier play if you want to do this.
No Galaxy Expedition because it just bricks us more. Hyper Galaxy is potentially strong, especially since it summons a Photon Dragon, but in practice its a huge minus if it whiffs and some boards don't have a 2000+ atk monster.
Don't be afraid to summon Photon Dragon by it's own effect if you already have Afterglow in hand, but always be sure your Prime Photon will stick before you specifically commit to it.
If you expect to go first games 2 or 3 just side in the Dragon Buster and equip it to Hope Harbinger. If you specifically want to go first though, the Warrior/Isolde version is probably better for it.
Have fun!!
