With the new support from the upcoming Cyberstorm Access and Maze of Memories, this deck has great potential to be a strong pick. Not only it has easily available Xyz summoning and powerful combos with 3 level 4s on board. It has access to resource loops, decent boards, and great follow up to be able to outresource the other players in a long game.
Constellar Caduceus as a deckmaster makes the deck extremely consistent as it enables full combos with any level 4 in hand and gives access to DARK and Spellcaster monsters, as well as searching Constellar Tellarknights, the main new piece that enables this deck.
The deck also has acess to great archetypal removal or interruption through Satellarknight Skybridge (which is now searchable and can be reused with Tellarknight Constellar Caduceus), Stellarknight Triverr, Stellarknight Delteros, Constellar Pleiades and Tellarknight Altairan. As well as cards like Exciton Knight.
It is worth experimenting more and might get Caduceus banned as a DM. Who knows?
