Notes & Combos
The deck is really expensive and hard to play properly so don't waste your dust if you don't know what the deck does. I highly recommend watching gameplay of N3sh playing this deck on either his or DB Grinder's channel for learning how the deck functions.
This is as nonlinear as a deck gets, but the goal going first is basically to get Cartesia on the board and Albaz in hand or on the field (or Shrouded Dragon/Bystial Aluber on the board instead) and perform a "manual Branded Fusion". Quem, Albion, Dis Pater and Bystials help you achieve this while also giving you bodies to link/synchro/fuse with.
Mainly you want to end on some combination of: Seals, Dis Pater (in grave is fine if you have Regained), Regained, Beast, Granguignol (on field or grave), Baronne (mostly used as follow-up but crazy hands can also end on him).
This is why you use Branded Fusion only as a last resort or as a board breaker. DON'T spend your valuable Quem and Saronir dumps just to search it and lose to Ash every time.
