"Invoked", known as "Invoked Beast" (召喚獣 Shōkanjū) in the OCG, is an archetype of Fusion Monsters debuting in Booster SP: Fusion Enforcers.
Design-wise, the archetype consists of "Invoked" Fusion Monsters who are seemingly Summoned through magic powers by sorcerers.
Individually, each "Invoked" represents a different Attribute, with their Fusion Materials being "Aleister the Invoker" plus one monster of their specific Attribute, and are named after historical or mythological elements related to said Attribute. They also contain the staff of "Aleister" somewhere in their artworks, but much brighter than the original.
The archetype's main goal is to perform Fusion Summons of the "Invoked" Fusion monsters, relying on "Aleister the Invoker" and the versatility of "Invocation" to do so. With the proper set-up, it is possible to build a very consistent and recursive strategy, in which "Magical Meltdown" searches "Aleister", which in turn searches "Invocation". Then, the Fusion Summons can be performed and once "Aleister" is banished by "Invocation", it can be later recycled, creating a loop in which the player is granted to have access to the resources needed to keep on Fusion Summoning turn after turn. Also, "Invocation" can be used to banish troublesome monsters from the opponent's Graveyard in the process.
The said Fusion monsters are also very versatile, having effects that range from limiting the number of times a player can activate monsters' effects and attack, flipping monsters face-down, negating cards' effects and attacking multiple times. The variety of Attributes and the ability of "Invocation" of banishing monsters from the Graveyards also enables the Deck to use powerful engines, like the "Windwitch", that is used to Synchro Summon "Crystal Wing Synchro Dragon". Also, hand traps like "Effect Veiler", "Maxx "C"", and the Yo-kai Girls can be given a last utility, by being used as Fusion Materials.
- "Chain Disappearance" can be used to banish all copies of "Aleister" at the time it is Normal Summoned. Bear in mind, though, that if "Invocation" is sent to the Graveyard, by a card like "Twin Twisters", "Foolish Burial Goods", etc, those copies can be easily retrieved.
- "Imperial Iron Wall" can be used to prevent the "Invoked" player from banishing monsters from their opponent's Graveyard, and can also disable the powerful effect of "Invoked Mechaba", since it will not be able to banish the card it would have negated.
