Okay, so I removed Bystials to make space for other new cards and support, so here is the whole decklist and what every card does:
MAIN:
3x Aluber, the Jester of Despia: The deck's main searcher. You're dead if it gets ashed.
3x Fallen of Albaz: The core and most important card of the whole deck.
2x Blazing Cartesia, the Virtous: A fusion material for two differend monsters: Sanctifire and Granguignol.
1x Guiding Quem, the Virtous: Can be used sometimes, but it's very gimmicky. Mostly there just for rare occasions it can be good for doing it's effect or summoning Sanctifire.
1x Albion, the Shrouded Dragon: Just an Albaz replacement for fusion summoning from grave.
1x Gimmick Puppet Nightmare: Only there for fusion material for all monsters that need a DARK monster as a fusion material. The plan is to put him to GY and then summon him to your opponent's field during their standby phase by Sanctifire's effect to make them unable to summon other monsters.
1x Tri-Brigade Mercurier: A hand trap that can be used if you control an Albaz fusion monster (which you most likely will if you're going first)
1x Despian Tragedy: Can be used to search Aluber if foolished to the grave.
3x Ashh Blossom & Joyous Spring: I don't need to explain. Basically a combo ender for your opponent.
1x Branded Lost: Used to recycle Albaz everytime you fusion summon using him.
3x Branded Fusion: I think it's very self-explanatory.
1x Foolish Burial: As I already explained, it can come in handy for sending fusion materials to the GY.
2x Fusion Deployment: Can be used to add either Albaz or Cartesia to your hand for summoning.
2x Lightning Storm: I don't side it. It's just way too powerful and useful.
1x Monster Reborn: You can summon back a destroyed boss monster or Albaz and use it's effect to fusion summon using one of the opponent's monsters.
2x Polymerization: Can be used for fusion summoning pretty much anything, but the obvious target for it is Guardian Chimera since it cannot be summon by Branded fusion.
1x Super Polymerization: If you still have 1 card in your hand at the end of you turn, you can set Super Poly and use it to clear the opponent's board of their insane bosses.
3x Branded in Red: The second strongest fusion card you need. Returning Albaz to hand and then fusing him again is just insane, as well as doing the sam with Aluber to summon Masquarade.
3x Triple Tactics Talent: If you get handtrapped, you can take some ground back by using one of Tactics' effects.
2x Branded Opening: If you don't open with Aluber you can search him. Otherwise Opening is just a discarding material if you don't need to use it.
1x Called by the Grave: If you get Ashed, you can just negate the Ash and continue without the fear of getting Ashed again.
1x Crossout Designator: Again, can be used to negate Ash or Nibbiru or any other hand trap.
1x Branded Retribution: A negate with a GY effect to recycle one spell back to your hand from the GY.
3x Infinite Impermanence: Can be used either as a hand trap if your opponent goes first, or as a negate and a zone lock if they go second.
EXTRA:
Guardian Chimera: A very powerful boss monster for going both first and second. Can make you advantage and make the opponent disadvantage at the same time.
Albion, the Sanctifire Dragon: very good monster. You can either summon Gimmicky Puppet Nightmare to your opponent's field during their turn to lock them from summoning or summon Albaz to your field and another monster from your GY to their field and then fusion summon using Albaz's effect to fusion summon during their turn.
Borreload Furious Dragon: A mostly generic fusion target for super poly or Albaz. Can be used to detroy itself and another monster your opponent controls.
Mirrorjade, the Iceblade Dragon: The boss monster of the deck. You can use it's effect to quickly remove a good combo starter or extonder from opponent's field before thy use that monster's effect.
Lubellion the Searing Dragon: Used in the main combo to summon Mirrorjade by shuffling itself from the field and Albaz from the GY as fusion materials.
Alba-Lenatus the Abyss Dragon: Can attack multiple times to clear opponent's board or can be set to the GY by Mirrorjade's effect to add a fusion card to your hand.
Despian Quaeritis: Pretty powerful to trigger it's effect when your monster would be attacked by an opponent's boss with the higher attack to make the opponent take the damage and lose that same monster. You can also trigger it's effect EVERY turn, so you can just make all your opponent's monsters have 0 ATK nd the beat over all of them.
Granguignol the Dusk Dragon: Since most of the extra deck monsters featuring Albaz as a material have good GY effects at the end phase, you can send them there for free using Granguignol's effect. Is also a good fusion that has Cartesia as a material.
Albion the Branded Dragon: Can be used either to fusion summon using his effect or to be sent to the GY for his GY effect.
Brigrand the Glory Dragon, Titaniklad the Ash Dragon and Rindbrumm the Striking Dragon: only there for their GY effects.
Masquarade the Blazing Dragon: Very good since now the opponent has to pay 600 LP every time they activate an effect, so it can take out a very good chunk of their LP.
Predaplant Dracostapelia: Kinda generic and permanently negates a monsters effect.
SIDE:
2x Nibiru, the Primal Being: Use it aginst very combo-heavy decks WHEN THEY FINISH THE COMBO, because that's how you can make the most out of it. Otherwise they can just continue if you chained Nibiru to an effect and it then resolves.
3x Droll & Lock Bird: Makes your opponent unable to search anything, practically ending their combo right there and then.
3x Dark Ruler No More: If you go against Stardust synchro or Utopia or any other with a bunch of negates on their field, you can just negate them and continue safely.
3x Cosmic Cyclone: Very good form of backrow removal.
1x Skill Drain: Side ONLY under very dire sircumstances, as it also drains you, as well as the opponent.
3x Evely Matched: If you survive their battle phase, use ias a hand trap and remove the entirety of thier field from existance.
