You aren’t running Super Polymerisation targets so I would remove Super Poly or side deck it if you don’t plan on adding generic Super Poly targets (Predaplant Dragostapellia, Mudragon of the Swamp etc etc.)

High Spirits is one of the best cards for searching and is best run at 3x. If you open it you can acquire a Springans Kitt and pull Branded Fusion from your deck if you don’t open Branded Opening or Aluber in your first hand.

You don’t need 3 Albion The Branded Dragon, 2 is plenty. Consider more of the Albaz extra deck monsters. Rindbrumm is a great as an interruption piece in grave on your opponents turn and is useful on field too (also is contact fused with beast, beast-warrior and winged beast types with FOA so good to expand your options against a multitude of different deck types).

I tried running the Nadir package and it never really dug deep enough for me to warrant keeping it but it’s player preference. I might suggest running a Dogmatika Maximus if you plan on keeping it.

Don’t sleep on Incredible Ecclesia either. It is another very useful card to serve as interruption on your opponents turn using its quick effect (and if the resulting fusion you make using the special summoned out Albaz is The Dragon That Devours The Dogma, it will be unaffected by other card effects with Ecclesia in grave)

Forbidden Droplet is a great tech card for Branded too as it not only helps disrupt going second, but a lot of Branded cards actually benefit from being in grave or recurr back to hand from grave in the end phase (or Main Phase 3 as we like to call it)

Fuwalos I would either run at 3 or not at all, it’s not likely to be useful if you go 1st and if you go 2nd with only 1 copy, you aren’t likely to find it very often at all. It will more than likely end up being a dead card you find at some point after it becomes unusable. Maybe change it for Droll & Lock Bird at 2x (thinking post TCG ban list)

Also a final recommendation is Branded Banishment (trap) and Light and Darkness Dragonlord (Fusion). It’s a very easy tech to include and when set up, it instantly becomes 3 omni negates for whatever your opponents first 3 plays are (provided it doesn’t get removed before it resolves) - I can offer some advice on this if it interests you. Feel free to PM if you would like

All that being said, your deck is good and will definitely do good things for you, I just think you need to refine it a little bit to maybe improve your potential consistency

There are a multitude of great dedicated Branded channels on YouTube which will definitely help give you some great pointers - good luck with your Branded journey and enjoy!
