The optimal opener will have you summon Junk Speeder using junk Synchron and Converter. You bring back a Synchron, and special summon Jet, Fleur, another Junk, and Stardust. Impatient people here will drop Nibiru on you, and if that happens search Stardust Illumination if you don't already have it or Foolish Burial in your hand. Otherwise search Arrive In Light.

If all goes well: Special summon Charge Warrior with Speeder and Jet Synchron. Draw a card off of Charge Warrior. Then activate AIL and special summon Crystal Wing. Activate AIL to draw Converging Wills, and if Brotaur is in your hand use Fleur Synchron's ability as chain link 2 to special summon him. Use Converging Wills' effect to special summon itself (and Brotaur if you didn't already do so) and use Brotaur to search for a Doppelwarrior off of Junk Synchron by discarding one card.

Special summon Hyper Librarian with Stardust Synchron and Brotaur, and then tribute your excess Junk Synchron to bring back Stardust Synchron. This lets you special summon Doppelwarrior.

Special summon Shooting Majestic with Converging Wills, Crystal Wing, and Doppelwarrior. Special summon Garden Rose Maiden with Stardust Synchron and a Dopeltoken and get Black Garden.. Resurrect Jet Synchron and use it and the other Doppeltoken to make Double Star Shamn. Now this is an important converging point because it will determine how you're going to use Black Garden. But now you want to activate it.

If you have your last Junk Synchron in-hand or an Ash (ideally a spare) or a usable Synchro Overtake: Summon Cosmic Blazar with Hyper Librarian, Garden Rose Maiden, and Double Star Shaman. Summon Accel Synchron with the Doppelwarrior and Junk Synchron. Mill a Stardust Synchron from your deck and raise Accel Synchron's level to 9 and use it and a doppeltoken to summon Baronne. Use AIL's effect to special summon the level 3 tuner in your hand (or use Synchro Overtake) and use your tuner and remaining doppeltoken to make Herald of the Arch Light. Use Baronne to destroy Black Garden, and then use Rose Garden Maiden's graveyard effect to resurrect Crystal Wing.

If all goes well you will be looking at a board with four omni-negates, one monster negate, and your opponent's board will be clogged down with tokens that effectively locks them out of a lot of actions and most forms of extra deck summons aside from a few specific cards.

Dkayed has a similar version of this combo but it lacks the Rose Tokens on the opponent's board in exchange for a few more draws off of Hyper Librarian. I personally find locking down the opponent's board more useful.

328-176-265. I also have put a number of matches on youtube too as furnaxikki.

It can unbrick your hand, and also it is great Ash Blossom bait in the event you have a good hand. Also, if I have it I can play through Maxx C and then drop it at the end to deck my opponent out.
