Synchron

The Synchron archetype treats the graveyard as its primary resource, constantly feeding monsters into it as Synchro Material and then drawing value back out through the triggers those monsters carry. Nitro Synchron replaces itself with a draw the moment it is used for its target Synchro Summon, Fleur Synchron drops a Level 2 or lower monster from hand to field mid-combo, and Synchron Explorer recovers any Synchron from the graveyard upon its own Normal Summon. Quickdraw Synchron accelerates the whole engine further by self-Special Summoning at the cost of discarding a hand monster, effectively turning dead cards into bodies on the field while simultaneously stocking the graveyard. Accel Synchron then acts as a level-tuning hub, sending additional Synchron monsters from the deck to the graveyard to adjust its own Level and climb toward higher-Level Synchro Summons.

Because so much of the deck's output comes from chaining graveyard triggers together, it strongly favours going first and establishing a Synchro Monster before the opponent can apply disruption. Steam Synchron and Formula Synchron both carry Quick Effects that allow Synchro Summons during the opponent's Main Phase, giving the deck a degree of interactive play even once a board is established. Satellite Synchron can Special Summon itself whenever any monster is revived from the graveyard, ensuring the deck rarely runs short of Tuner bodies to continue climbing. Synchronized Realm adds a supplementary pressure angle, dealing 500 damage each time a Synchro Summon resolves and turning a long combo turn into incidental burn that accumulates quickly.
