Notes & Combos
INTRODUCTION
This is a Synchrons deck where the core objective is to find safe ways to summon Junk Speeder (the main extender), which enables branching into a variety of synchro summons.
CORE STRATEGY
If going first, we play the infamous "Trishula-Omega-DisPater rip-a-card-from-the-hand" strategy, removing a total of 3 cards from the opponent's hand during mid combo, and ultimately transition into an end board of disruptions between level 8 and 10 synchro monsters.
If going second, we aim for an OTK by summoning as many level 8 and 10 synchro monsters as possible and, most importantly, Crimson Dragon. Crimson Dragon gives the option either to go into (1) Trishula for a non-targeted banish to help clear the opponent's board or (2) Trident Dragon for up to a total of 3 individual attacks of 3000 attack each. Choose between Trishula and Trident Dragon, depending on the opponent's board and current game state.
VARIATIONS
For the end board, I have tried a variety of different level 8 and 10 synchro monsters, including Chengying and Draco Berserker, for the more discretionary slots in the extra deck, but ultimately, I ended up personally feeling more confident with Dragite and Clear Wing.
For openers, I have tried the Kashtira engine for level 7's, which worked very well because Unicorn and Fenrir tend to bait out opponent's disruptions early on before getting into Junk Speeder, making the Junk Speeder play that much safer. However, I decided to remove Kashtira to fit in more copies of Stardust Trail, Stardust Illumination, and the Synchrons for consistency because I ran into too many unlucky cases where Revolution Synchron's or Tuning's effect milled one of those garnets into the GY, which disabled the deck from further extending during mid combo (e.g., unable to summon Stardust Trail to get into Accel Synchron and, also, unable to correctly adjust Accel Synchron's level due to not having the target Synchron in the deck anymore).
Besides for consistency, I find that having extra copies of Stardust Trail and Illumination enable some openers that would not be particularly viable otherwise (i.e., some variations of 4+4, 1+4+4, and 2+4+4), but there have also been times that I wished that they were Kashtira instead to help bait out interruptions early on.
Nonetheless, feel free to experiment on your own to find out which options work best for you.
I wish I could say more, but I am at the maximum character limit for this post :(

Please note:
(1) Some replays may show cards that are not in the final deck list (e.g., Chengying, Draco Berserker, and Nibiru) because I was learning and adjusting the deck over the course of the climb.
(2) I have included a few replays from the WCS Qualifier Event in addition to the ladder climb to showcase some matches, as I was doing both the ladder climb and event with the same deck at the same time.
Enjoy!!!
