Crystron is a Machine-type archetype that revolves around Synchro Summoning, and uses many tools to reach this goal. Their Non-Tuner Monsters can easily summon Tuner Monsters onto the field, and their Tuner Monsters can Synchro Summon during the opponent’s turn. The deck wins primarily by controlling the board as much as possible until it can extend into boss monsters such as Crystron Quariongandrax, or until it can swarm the field enough to threaten lethal damage.
Because this deck has been out of the meta for a while, we do not have enough statistics on the deck to generate an up-to-date breakdown. See below for the most recent available decklists.
1st Place – Anytime Tournament – April 28, 2021 – SHOMA
- Crystron Sulfefnir summons itself and destroys upon resolution, meaning that there is no activation window between when it hits the field and when it destroys a card (typically itself).
- All of the Crystron Tuners immediately Synchro Summon upon effect resolution, meaning there is, once again, no activation window between when their desired target hits the field and when the Synchro Summon takes place. This means that your opponent must disrupt your field in response to the Tuner’s effect in order to prevent the summon.
- If the opponent does disrupt the Tuner (noteworthy examples include Treacherous Trap Hole and Paleozoic Canadia), and you are now unable to Synchro Summon for any given reason, the Monster targeted by the effect of the Tuner monster is still summoned, and will remain on the field even if the Tuner is removed.
- The Tuner Monsters can only summon Machine-type Synchro Monsters with their effects, and you can only summon Machine-type Synchro Monsters during the turn in which you use a Non-Tuner’s Special Summon effect (excluding Crystron Sulfefnir). Additionally, when using their effects, as the Tuners can only Synchro Summon using themselves and the Monster they summoned, it is impossible to summon Crystron Quariongandrax on the opponent’s turn.
