Majestic Stardust

I am ecstatic for the new Stardust support  and I really like how they decided to bolster the power of the existing Majestic support. The deck functionally goes first since Stardust has many options to put up negates nowadays. You can get a pretty good endboard with a two card combo of just Junk Converter and Stardust Synchron. But you will get more out of it if you have Doppelwarrior as well.

Main Deck includes 3 Ash Blossom, 3 Quickdraw Synchron, 3 Stardust Synchron, 1 Stardust Trail, 3 Junk Synchron, 3 Junk Converter, 3 Doppelwarrior, 1 Stardust Xiaolong, and 1 Wish-Converging Dragon. Quickdraw Synchron is just Tzolkin fodder and I guess you can use it as a target for Shooting Riser Dragon if you decide to play things like Shooting Star Dragon, Stardust Warrior, or Satellite Warrior. Stardust Synchron is a level 4 Synchron tuner which is very good already and it searches basically most of your much needed Spells/Traps, but its sad that it doesn't search Synchro Chase but that is understandable. If you discard it off of Converter, its essentially a free extender from grave. Stardust Trail is a decent card since it is a level 4 extender, but its the primary target for Stardust Illuminate other than Xiaolong. Junk Synchron is bonkers of course. Junk Converter is grave set-up, a searcher, and it gives you an extender. Doppelwarrior is just here since it makes tokens. Xiaolong is another Illuminate target. Wish-Converging Dragon gets you to Majestic Star and Shooting Majestic Star.

Spells and Traps aren't surprising. 3 Tuning. 3 Stardust Illuminate which is a Foolish and level modulation. 3 Synchro Chase since it makes sure your effects go through. 1 ROTA. 1 Reborn. 3 Arriving Miracle which is just to get you to your Majestic monsters. 1 Called By since every play in this deck is just asking to be handtrapped. 2 TTT for the same reason. 1 Black Garden to either go with Garden Rose Maiden or Garden Rose Flora. Finally, 1 Majestic Mirage since it essentially makes your Shooting Majestic Star Dragon's 1 negate into 3 interruptions.

Extra Deck. 1 Ultimaya Tzolkin since it brings out either Moonlight or Crystal Wing. 2 Shooting Majestic Star Dragon which is an interruption going first and your OTK enabler going second. 1 Blood Rose Dragon since its a thing going second or you can take something like 1 of your Junk Speeders out and replace it with a normal Black Rose Dragon to use Blood Rose's second effect as another form of disruption probably. 1 Majestic Star Dragon which is just insane and it doesn't need to return to the ED if you have Arriving Miracle face-up. 1 Crystal Wing Synchro Dragon and 1 Blackrose Moonlight Dragon as Tzolkin targets. 1 of the original Stardust Dragon and 1 Stardust Spark Dragon. 1 Stardust Charge Warrior. 1 T.G. Hyper Librarian. 2 Junk Speeder. 1 Garden Rose Flora which is just Tzolkin fodder and a thing for Blood Rose, but you can switch it for Accel Synchron if you value the level modulation. Finally, 1 Garden Rose Maiden which is more Tzolkin fodder and it revives a Dragon Synchro from grave. It also searches Black Garden which can be used as an extender of sorts.

Side Deck is meh. 2 Nibiru. 3 Belle. 3 Majestic Absorption which is really only here for the equip effect going second. 3 Lightning Storm. 2 Forbidden Droplet. 2 Starlight Road because its a Stardust deck so why not.
