Yu-Gi-Oh! Best Synchron Deck Profile January 2024 (Full Combo Guide)

Yo! The Synchron King returns after his 8 year slumber. What could he possibly have to offer to the world after his long absence? Watch and find out.

JK! Man. 8 years since I've touched contemporary Yugioh. There are obviously lots of changes (RIP Level Eater!) but Synchrons have never been better. Speeder with a converter in the graveyard makes first turn GUARANTEED 4 omni negates with +11? SHEESH! See time stamps for combos, replays, small world mapping, etc!
Note that the two combo guides (Flow 2.0 & Flow 3.0) have Cosmic Quasar Dragon and no Ancient Fairy Dragon just to illustrate full GUARANTEED combo-potential should you not want to run Ancient Fairy Dragon & Secret Village. (BUT! If you summon Crimson Dragon BEFORE Librarian, then you have the extra counter and thus can just replace CQD with AFD).
Both replays (not the combo guides) do have the actual deck profile, however. To be honest, the combo guides were made before I thought about making Crimson prior to Librarian to then not need CQD. Definitely always make Crimson before Librarian to guarantee the 7 counters if you are running AFD.
