Got back into TCG during quarantine after a long hiatus. Synchros always have been my favorite amongst all other monsters and since I never got around into making a full deck back then, I thought it would be a good idea to make it now. After some trial and error I came up with this:
Summon Dux and Phalanx with Dragunity Whirlwind, synchro summon Vajrayana, equip then summon Phalanx with its own effect, normal summon Deep Sea Diva, then another one from the deck with its effect, then synchro summon Red Supernova Dragon.
Special summon Ice Bell, then Glass Bell, then Snow Bell, then synchro summon Clear Wing Synchro Dragon (first) then Crystal Wing Synchro Dragon (second).
Ideal conditions to bring Ruddy Rose Dragon: normal summon White Rose Dragon, then special summon from your hand or GY (can be sent there with Foolish Burial) one Red Rose Dragon. Synchro summon Black Rose Dragon, then using Red Rose's effect special summon Roxrose Dragon from your hand or deck, then all you have left to do is synchro summon Ruddy Rose Dragon using both monsters as materials.
OR (the hard, unorthodox way)
Synchro Summon Black Rose Dragon using Angraecum Umbrella and another level 4* monster, then you can clear the field, use Stardust Shimmer or Monster Reborn to bring him back, activate Double Summon and summon a level 3* tuner, then synchro summon Ruddy Rose Dragon. If you don't have Double Summon in your hand at the time, you can wait a turn, use Stardust Shimmer, then normal summon the level 3* tuner.
Tip: Once you clear the field with Black Rose Dragon you can freely use your Ice Bell to summon Crystal Wing Synchro Dragon
Disclaimer: I moved these cards to the side deck bc of how inconsistent this combo was during each duel (it can work but its kinda hard to pull off in THIS deck, might have to make a seperate one just for that). Anyway.....
Using One For One, summon Glow-Up Bulb, send Dandylion to graveyard. Summon 2 tokens, then synchro summon Formula Synchro. After that, normal summon Debris Dragon then using its effect, special summon Dandylion. Synchro summon Stardust Dragon, then special summon 2 tokens with Dandylion's effect, activate Glow-Up Bulb from the GY, then Synchro summon T.G. Recipro Dragonfly. Once they're all on the field synchro summon 1 Stardust Sifr Divine Dragon.
That's all that is packed in this deck. The rest of the cards are there for support, support meaning excessive drawing power using cards such as Graceful Charity, Pot Of Greed, Morphing Jar, Magical Mallet, Reload (x3).
29/01/2022 edit:
Deck can be tuned to be tournament friendly by removing Graceful Charity and Pot Of Greed for Magical Mallet/Card Destruction/Card Trader (your choice).
Crystal Clear Wing Synchro Dragon summon conditions (1 turn summon): you need Righty Driver, Double Summon and Angraecum Umbrella, plus one level 4* monster in your hand or GY. Activate Double Summon then normal summon Right Driver. Summon Lefty Driver using Right Driver's effect then once both are on the field Synchro summon Tatsunoko. Normal summon Angraecum Umbrella, activate its effect, pick a level 4* monster, special summon it, then synchro summon Clear Wing Synchro Dragon. Once Tatsunoko and Clear Wing Synchro Dragon are on the field, you can freely summon Crystal Clear Wing Synchro Dragon.
