First, I'd like to point out that it's no faster than anything else. Second, it's not a good combo because you lose two cards. And Galaxy-Eyes isn't very good outside of Disaster Dragons...
This combo only requires "Dux" in your hand and "Phalanx" in your Graveyard, and it is incredibly simple to set up with the help of "[[Dragon Ravine]]". With it, once per turn, you can discard a card to either add a "Dragunity" monster from your Deck to your hand or send any Dragon-Type monster from your Deck to the Graveyard - essentially turning any card in your hand into either a "Dragunity" version of "[[Reinforcement of the Army]]" or "[[Foolish Burial]]", which makes combos easy.
Another good strategy for synchros is using "[[Dragunity Pilum]]" and "[[Dragunity Militum]]." Pilum allows you to summon a Winged-Beast type Dragunity from your hand and equips itself to it, while Militum can special summon equipped Dragunities, allowing for a fast level 7 synchro for monsters like "[[Black Rose Dragon]]" and "[[Ancient Fairy Dragon]]."There is another combo with "Militum" using "[[Dragunity Partisan]]".The effect of "Partisan" when is normal summoned is the same than Pilum so you can use this combo to Synchro summon level 6 monsters like "[[Brionac, dragon of the ice barrier]]", "[[Dragunity Knight - Gae BulgTrident]]." or "[[Dragunity Knight - Gae Dearg]]".
However, the "Dragunity" monsters have many alternate strategies. Even without Synchro Monsters, the archetype can hold its own in battle: "[[Dragunity Legionnaire]]" takes out tough monsters with its effect - you can send an equipped Dragon-Type monster to the graveyard to destroy one of your opponent's face-up monsters. This is especially useful with "[[Dragunity Aklys]]", as when it is equipped and sent to the Graveyard, one card on the field is destroyed. As such, one of the main "Dragunity" combos is to Normal Summon "Legionnaire", equip "Aklys", and send it to the Graveyard to destroy one your opponent's Face-up monsters and another one of his/her cards, in a devastating one-two punch that costs you nothing. However, this can be countered with "Enemy Controller"-since "Aklys" activates first (as Chain Link 2), you can chain "Enemy Controller" and steal their monster (this works if you only have one more monster) to get it killed by "Phalanx" effect. This also works with the second effect of "[[Dragunity Knight - Vajrayana]]", which can send a card equipped to itself to the Graveyard to double its own ATK until the end of the turn (which usually isn't used since a "Stardust Dragon" is preferable). If you equip and then send "Aklys" to the Graveyard, you will end up with a 3800 ATK monster that turn while destroying one of your opponent's cards, allowing for big finishes.
