Combo Tips
Key information to understanding Galaxy combos.


Tachyon boards lean heavily on their backrow, some of which can be activated from the hand. When a combo refers to a Tachyon S/T, it refers to a Tachyon Spell or Trap of your choice other than Seventh Tachyon.
Tachyon Transmigration(s) and Tachyon Spiral of Destruction are the most common choices. Transmigration is not hard once per turn, and Spiral can add Transmigration to hand for another use or counter Kaiju- and Super Polymerization-style removal.


Divine Shadow Dragon Dragluxion is a key element of Galaxy combos. In addition to its search, it can summon powerful boss monsters and attach Galaxy monsters from the Extra Deck to them as material.
In general, there are three options to consider.
• Attach Galaxy Satellite Dragon, either to Number 107: Galaxy-Eyes Tachyon Dragon for offense or Number 38: Hope Harbinger Dragon Titanic Galaxy for defense.
• Attach a monster you wish to summon during your next Standby Phase with the effect of Galaxy-Eyes Cipher X Dragon.
• If you do not need extra material, preserve your Extra Deck by not attaching. Note that relying on Tachyon Cloudragon to replenish material is vulnerable to GY disruption.

There are some combo lines where the most effective way to get monsters into the GY is by detaching them - and Number 97: Draglubion does that without sacrificing endboard strength. Not all boss monsters can detach material on demand like Draglubion can.
Additionally, should you be willing to consume more of your extra deck, almost any Tachyon combo can summon Draglubion in place of its final monster to append a 3k body to the board. This is done at the player's discretion.


For the most part, yes. Both serve as targets for Schwarzchild Infinity Dragon that go plus after being detached. Galaxy-Eyes Afterglow Dragon requires a copy of Galaxy-Eyes Photon Dragon to be included as well.
Afterglow allows Tachyon Cloudragon to be a one card combo in non-Bystial variants, works under the effects of Dimension Shifter, is potent on offense, and plays more reactively into Bystials. Galactic Sprial offers better grind and enables a few re-leveling combos. It is up to the player whether to run one or both of these techs.



The above icons represent the number of Tachyon S/T searched, Galaxy Hundred Extra Deck banishes, and Branded Regained draws obtained through the combo. Two draws or banishes implies a way to trigger the effect on the opponent's turn.
NS - Normal Summon | SS - Special Summon
GPD - Galaxy Photon Dragon | GEPD - Galaxy-Eyes Photon Dragon
Number monsters are referred to by their number.
Some card images have overlays. These denote either important xyz materials (on xyz monsters) or notable cards in hand.
Absolutely. Though varations for some combos are included, we prioritize the most efficient ones possible.
There may be situations where you prioritize Galaxy Hundred banishes or Tachyon Transmigration(s) at the expense of other interaction, shift the weight of Galaxy-Eyes Cipher X Dragon vs Starliege Photon Blast Dragon protection, account for Bystial threat differently, or reevaluate Seventh Tachyon card advantage.
Ultimately, there is flexibility; the written combos identify patterns you can use to your own ends.
The number of possible 3 card combos is immense. At most we can include a few examples.
Learning how to sequence 3+ card combos is a skill gained by mastering fundamental lines. Once you develop it, you will be better be able to play around handtraps and maximize card advantage.
