Guardian

"Guardian" (Gādian) is an archetype of monsters with various Attributes (primarily DARK and WIND) and Types (primarily Fairy and Fiend) used by Rafael in the Yu-Gi-Oh! anime, as well as Apollo and Diana in the Yu-Gi-Oh! ARC-V anime. The original "Guardian" monsters each have a corresponding Equip Spell Card.

"Celtic Guardian", "Winged Dragon, Guardian of the Fortress #1", "Winged Dragon, Guardian of the Fortress #2", "Guardian of the Labyrinth" and "The Reliable Guardian" are not "Guardian" cards as they do not include in their Japanese names. As such, the only "Guardian" support card in the TCG/OCG, "Arsenal Summoner", have specifically excluded them. In other TCG languages, "Arsenal Summoner" have also excluded the following cards:

• French: "Il Blud", "Mid Shield Gardna", "Mysterious Guard" and "Phalanx Pike"


• German: "Gravekeeper's" cards, "Guard Penalty", "Kid Guard", "Lava Battleguard", "Swamp Battleguard", "Obnoxious Celtic Guard" (now renamed) and "Fusion Guard"


• Italian: "Golem Sentry", "Lava Battleguard", "Swamp Battleguard", "Mid Shield Gardna", "Obnoxious Celtic Guard" (now renamed) and "Hedge Guard" (which doesn't have "Guardiano" in its name)

The core "Guardian" monsters were initially released in Dark Crisis and re-released in Dark Revelation Volume 1. They can only be Summoned if the player already controls their corresponding Equip Spell Card. However, they can still be Set without controlling their respective Equip Spell Card. The Equip Spell does not have to be equipped to their corresponding monster, and due to their Summoning conditions, usually cannot be. "Guardian Eatos" is the only one of the "Guardians" with an associated Equip Spell Card who can be Summoned without restrictions.
