This card can give "Hieratic" Decks access to Level 8 Synchro options, in addition to the traditional Rank 6 Xyz.
This card is part of the "Galaxy" archetype, so it's possible to use its support cards, like "Galaxy Zero".
This card can be Special Summoned with the effect of "Dragard", as it has exactly 1000 ATK.
This can be used in a combo with "Hieratic Dragon of Nuit" that is already on the field. Normal Summon "Dragard" and Special Summon this card from your Graveyard. Then Tribute it for the effect of "Dragorado", targeting "Nuit". The effect of "Nuit" will then Special Summon "Galaxy Serpent" right back, which can be combined with the now Level 8 "Nuit" for a "Trident Dragion" or a Level 6 Synchro Monster with "Dragard".
