Synchron

Synchrons are an archetype of Tuner monsters, except "Synchron Explorer" and "Synchron Keeper", used by Yusei Fudo and Sherry LeBlanc.

Some "Synchron" monsters have a corresponding "Warrior" Synchro Monster that requires it be used in the Synchro Summon and their Levels go from 1 to 5 in this order:
 * Star.png: Turbo Synchron, Changer Synchron, Unknown Synchron, Mach Synchron and Mono Synchron
 * Star.pngStar.png: Nitro Synchron, Fleur Synchron, Formula Synchron and Synchron Explorer
 * Star.pngStar.pngStar.png: Junk Synchron, Steam Synchron and Drill Synchron
 * Star.pngStar.pngStar.pngStar.png: Road Synchron, Hyper Synchron and Bri Synchron
 * Star.pngStar.pngStar.pngStar.pngStar.png: Quickdraw Synchron and Synchron Keeper

"Hyper Synchron", "Quickdraw Synchron", "Changer Synchron", "Bri Synchron", "Mono Synchron", "Unknown Synchron", "Steam Synchron", and "Mach Synchron" do not have Warrior counterparts. Each "Synchron" with a corresponding "Warrior" is a different Attribute ("Steam Synchron" is the only WATER "Synchron" monster). Also, every "Synchron" apart from "Junk Synchron" is a Machine-Type monster. Recently revealed "Synchrons", "Changer Synchron" and "Bri Synchron", do not have their Synchro counterparts, but can change Battle positions of an opponent's monster the ATK of a Synchro monster. Also, they have gotten a new support cards, "Synchron Explorer" and "Necro Linker", who can revive any "Synchron" tuner from the Graveyard.

"Formula Synchron" is the only Synchro Monster in the "Synchron" archetype so far.

Interestingly enough, the original three Synchron Tuner monsters ("Junk Synchron", "Nitro Synchron", and "Turbo Synchron") have base colors that are complimentary to their first Synchro Monsters:
 * "Junk Synchron" (Orange) into "Junk Warrior" (Bluish-Purple)
 * "Junk Synchron" into "Junk Berserker" (Crimson)
 * "Junk Synchron" into "Junk Destroyer" (Dark Silver)
 * "Junk Synchron" into "Junk Archer" (Orange)
 * "Junk Synchron" into "Junk Gardna" (Green)
 * "Nitro Synchron" (Red) into "Nitro Warrior" (Green)
 * "Turbo Synchron" (Green) into "Turbo Warrior" (Red)
 * "Road Synchron" into "Road Warrior"
 * "Drill Synchron" into "Drill Warrior"
 * "Fleur Synchron" into "Chevalier de Fleur"

Weaknesses
When using a "Synchron" Deck that relies on using "Quickdraw Synchron", you'll be discarding a lot of monsters that if the "Synchron" Synchro Monster gets destroyed, you will have nothing to protect your Life Points. To counter this, add cards that can protect Synchros or add cards that negate card-destroying effects like "Royal Decree", "Dark Bribe", "Interdimensional Matter Transporter" or stop them from being removed from play with "Imperial Iron Wall".
