Class Card

Class Cards (クラスカード) are items created for the Ainsworth Holy Grail War in the place of Servants. There are two sets, the first appearing within Fuyuki and the second being in the hands of the Ainsworths.

Nature
Each of the seven cards correspond to one of the seven Servant Classes, utilizing the default class imagery to mark them. They draw out the power of Heroic Spirits, and the Mage's Association is unable to analyze them in any manner. The cards have a portion of the Heroic Spirits power sealed inside them, and it can be said that they are the Heroic Spirits themselves.

They can manifest by gathering prana from the land. Those from the first set are shown to be deteriorating when manifested, deviating from their original appearance and shown no longer have any of their reasoning. Archer from the second set is able to partially manifest while keeping his form. The Heroic Spirits form around their Class Cards, utilizing them as their heart.

It is possible utilize the power of the cards with a Kaleidostick or by being one of the Ainsworth's creations. With the Include: Limit Expand method, it temporarily materializes the weapon or Noble Phantasm of the hero until the Card is Unincluded. The true purpose of the Cards is to temporarily become a hero by accessing their full abilities. Install: grants the Noble Phantasm, appearance, and skills of the Heroic Spirit.
