Summon All Assault Mode Monsters !! Assault Mode DECK Dezember 2025 - YUGIOH

"/Assault Mode", known as "/Buster" (／スラッシュバスター Surasshu Basutā, read outloud as "Slash Buster") in the OCG, is an archetype of Effect Monsters that are powered-up versions of already-existing Synchro Monsters, which are Special Summoned by using "Assault Mode Activate", "Assault Mode Zero" or "Assault Reboot" on the corresponding Synchro Monsters. Those versions have the same name as its counterpart, but with "/Assault Mode" at the end. Both Yusei Fudo and Jack Atlas used the "/Assault Mode" counterparts of their monsters in the non-canon episode Evolving Duel! Stardust VS Red Demons.
