It's quite simple actually;

Boosted Gear < Scale Mail < Illegal Move Triaina < Juggernaut Drive <= Cardinal Crimson Promotion < Pseudo Dragon Deitifcation < Diabolos Dragon God.

That is currently how it sits. Besides these forms, an AxA and ExE form have also been hinted at. With the AxA form being the manifestation of Great Red's powers, and the now 8 mutated pawn pieces perhaps being the key to unlocking it.
