Solfachord Primoa is a one-card combo that ends on an omninegate with GranSolfachord Coolia and a pendulum scale from 0 (or 1) to 9, also Nibiru proof. This deck uses that interaction with Fairy monsters, but it's possible to go in an EARTH direction too.
I decided to follow the Fairy direction because of the Darklord cards, which are pretty good but lock you. Despia cards work very well with the Darklord cards, giving you more resources with the fusions, and recursion with Branded Regained and Despia, Theater of the Branded + Aluber the Jester of Despia. Lastly, the Purrely cards are here for support and an extra interaction, but are not very consistent.
The Darklord fairy lock is kind of hard to work around. I tested Madolche, Melodious, and Trickstar, but the archetypes listed above provided the most consistent results. If a new strong fairy archetype releases, it'll probably work very well with this deck master, but for now, I'm happy with this list.
