Zero Optima is written as "Zero Optima X [Text]" in the card text, where X is a numerical value greater than 0. This ability counts the number of cards with Ignition Icon in the Resource, and if the number is equal to or greater than X, allow the player to use the ability written on the [Text] portion.
Prior to July 2020 rule update, Zero Optima is treated as a classification of ability similar to startup, automatic, and continuous ability instead of a keyword ability.
The current reminder text of Zero Optima is shown below:
Zero Optima X (Available if there are X or more cards with Ignition Icon in your Resource.)
Zero Optima is the ability that activated by the Blue Dragon Miko, Yui's desire of innovation to "optimize the world". By implementing an overwhelming parallel calculation using the power of dragon, it aims for complete elimination of the irregulars. The accuracy of Zero Optima shows an exponential rise by increasing the dragon power that is being used.
Similar to Evol Seed and Alter Force, it also has an influence on the other worlds and their Miko through the Card Device. Moreover, its compatibility with the Card Device is extremely high compared to ability manifested from the other Dragon Miko's wishes. As a result, Zero Optima that was created to eliminate the irregulars, contains a contradiction by being an irregularity itself.
As of now, Schuster is unable to grasp Zero Optima.
