Hi, let me comment the deck profile :
-for the new stardust ratios I would play 1 Trail/ 2 Synchron instead of 2/, the reason being that Synchron is not a brick in your hand if you Connector, while you don't want to draw Trail in your starting hand, instead you want to send it to the graveyard with Stardust Illuminate or Foolish Burial.
- Rush Warrior, Road Synchron and especially Quickdraw are useless in this list because the deck revolves more around summonning the big dragons that the warriors. Only Satellite Warrior is viable, and you can't use Quickdraw to summon it. Only play Quickdraw if your deck includes Ultimaya Tzolkin.
- Because nothing banishes itself from GY, DDR is sorta useless, you should get a 3rd Living Fossil instead.
-Xiaolong does nothing, you would be better with another Synchron Carrier or Doppelwarrior, a combo piece that is really needed (by the way, Doppelwarrior is way better than Xialong, it does the same but much more).
-Raigeki and Feather Duster are also useless in the deck because the big dragons have omninegates that destroy so, again, you're better off with more combo pieces. Also you should think about including Psy-Framegear Gamma in the deck to negate a Ash Blossom on your Speeder, and it would provide board advantage !
