Ion

"Ion" (Japanese イオン, Ion) is an archetype of cards used by Gya Musenji in the Yu-Gi-Oh! UnION series. The theme revolves around swarming the field during the early stages of the game in order to Ionose Summon their "Ion-Eyes" Boss Monsters, which then proceed to dominate the field through a range of disruptive card effects. The members of this theme are supported by the "REACT-Ion" archetype of Spell / Trap Cards.

Play Style
Typically, Ion Decks run multiple copies of their Main Deck Boss Monster, "Ion-Eyes Dragon", which is needed to Ionose Summon their more powerful components such as "Ion-Eyes Catalys Dragon". Despite being a Level 9 without a reliable way of Special Summoning itself, "Ion-Eyes Dragon" is typically added to the hand via cards such as "REACT-Ion: Preparation" and then by placing "Proton Strike Dragion" and "Electron Storm Dragion" into the.

A common combo is to Pendulum Summon "Ion-Eyes Dragon" in this way, alongside "Ion Conduit". In doing this, the player will be able to "Ion Conduit" by its own effect, Special Summoning "Proton" and "Electron" from the Pendulum Zones and providing the sufficient Ionose Material Monsters to Ionose Summon "Ion-Eyes Catalys Dragon".

Due to this, both "Proton Strike Dragion" and "Electron Storm Dragion" are typically run at 3 copies each. This means that the Ion Tag is less frequently utilised in an Ion Deck than in most other Ionose Summoning Decks. As a result, the Ion Tag can be exploited to different lengths, by providing either more monsters to attack with or Synchro and Xyz Material Monsters for their respective Summons.
