Resource (リソース Risōsu) is a mysterious energy required by the Z/X.
In the Z/X - Zillions of enemy X- TCG, Resource is the zone to put the cards used by the player to pay the Cost to play Z/X, Event, or Z/X abilities. Cards can be put into Resource either during the Resource Phase or by card's effect.
Because flesh-and-blood humans cannot approach the BP, its connection to the Z/X remains an understudied field of research. Resource is considered to be the source of Z/X ability to function, and they cannot maintain their presence in our world if they lose this energy.
Powerful Z/X need to consume vast amounts of Resource, and due to this, they cannot go far beyond the periphery of the BP. Conversely, Z/X that appear far from the BP are relatively frail. All Z/X can sense where Resource pours from and how much there is in order to properly consume it, with varying degrees of awareness. As a result, it is possible to measure how strong a Z/X is based on how far away it is.
