The goal ist to set up a board with up to 4 disruptions first turn and win the game with high-ATK monsters. The deck is pretty consistent because it has many search effects included.
Some monsters can be summoned easier, if there is already a “Photon/Galaxy”-Monster on your side of the field. So its important to get any monster on board without using your normal summon.
For the extra Deck you can play nearly all Rank 4/8 XYZ, as well as a variety of Link Monsters. In this profile I only show my selection.
The Side Deck can be filled with backrow removal, floodgates, handtraps and other “Galaxy“-cards
Here a short description for the Main Deck cards:
Galaxy-Eyes Photon Dragon:
Important for Rank 8. Summoning/Effect-Condition for some other cards, especially because he got the „Photon“ and „Galaxy“ in its name. The own effect is nearly irrelevant.
Galaxy Knight:
Most important normal summon and a one-card-Rank 8. Can be searched, so i advise to play only 2 copies to avoid bricky hands, playing 3 is also possible (especially when also playing Pot of Desires)
Galaxy Brave:
Free special summon, requires a „Photon“-Monster in hand. Material for Rank 8 or Rank 4, also can be a good beatstick. Hard once per turn, so I only play 2.
Galaxy Soldier:
Searches all „Galaxy“-Monsters. Discard the Photon Dragon for the effect of Galaxy Knight. Soldier is also an easy way to Cyber Dragon Infinity.
Galaxy Wizard:
Also a normal summon. Searches any „Galaxy“-Card. Great combo extender, but normal summoning him may conflict with the Knight. You can also play 1 or 3 copies if you want to.
Galaxy Cleric:
Good card for turn 2/3. Recycles cards and lets you draw 2. Can be sided out if necessary (or cut completely).
Photon Vanisher:
Free Special Summon when you control any „Photon/Galaxy“-Monster. Searches the Photon Dragon and is perfect material for a Rank 4 or Link.
Photon Advancer:
Also a free special summon for a rank 4 or Link, but needs a „Photon“-Monster on field. I prefer him instead of Photon Thrasher, because Trasher usually bricks after turn 1. Playing Thrasher is still an option you may consider in your build.
Photon Orbital:
Most important searcher in the deck. Can search any „Galaxy/Photon“-Monster. Is also an equip for ATK boost and battle protection.
Spells:
Photon Sanctuary
2 Photon-Tokens, free Solflare Dragon, no once per turn…nothing more to say
Galaxy Expedition:
Summons one high-lvl Monster from your deck. Great combo extender. I advise definitely playing a playset.
Galaxy Trance:
Also a great combo extender or comeback card, but needs graveyard setup and blocks you from summoning Cyber Dragon Infinity. Playing a playset is possible, but not necessary imo.
Galaxy Zero:
Searchable Monster Reborn.
Reinforcement of the army:
For searching Vanisher and Advancer.
Monster Reborn:
Monster Reborn ;)
Called by the grave:
We got many searches and combos, so we have to protect us from handtraps. Can also be an interruption in your opponents turn.
Trade In:
Draw power. We play many lvl 8. We can easy discard the Photon Dragon for Knight’s effect.
Tachyon transmigration
One more negation for all your opponents effects in one chain. Needs a Galaxy-Eye Monster on our field to be activated. Can also be sided out or bumped to 3.
