Notes & Combos
I picked up this deck for this event because I somehow have a lot of Royal Synchron cards and never really had a chance to use it. Synchron builds can differ wildly between players and there are no real concise guide on Youtube so a lot of combos I had to learn on the fly. This is a solitaire deck, if your Junk Speeder resolves, you win the game. There are a lot of ways to get into an unaffected Junk Speeder or one protected by Baronne.
Some takeways from my climb: the Adventurer engine sets up free lvl 7 and 4 bodies to facilitate an unaffacted Junk Speeder using Accel Stardust. Even if you just have Fateful Adventure, you can use it to Chain Block Speeders summon effect from Ash Blossom. The Superheavy engine can bridge into Junk Speeder by using Diabolantis. Accel Synchron first to dump Revolution Synchron, reduce its level to 2 and combine it with the lv 8 Diabolantis to make Baronne to insulate your Junk Speeder.
The ideal boards gets you 3 handrips, two negates, a pop, and however many draws you get from Hyper Librarian. Going second... we don't take about going second. Just hope your draw your power spells.
