Although most Koa'ki Meiru monsters have difficulty staying on the field, a few of them work incredibly well together, sharing types or common reveals that help ensure their survival on the field.
With the release of the [[Machine Emperors]] in the [[OCG]] the Koa'ki Meiru can evolve and expand their [[Anti-Meta]] to an anti-Synchro level, the advantage of running the Machine Emperors lies in the self-destruction effects that is common among the Koa'ki Meiru and also that all of them except ["[Meklord Emperor Wisel ∞]]" are not [[DARK]] or [[LIGHT]] attribute, rendering them immune to the [[Anti-Meta]] effects shared among the archetype, while also combining with the effect of "[[Iron Core Specimen Lab]]" to search for key monsters such as "[[Koa'ki Meiru Urnight]]".
* "[[Koa'ki Meiru Urnight]]" and "[[Koa'ki Meiru Crusader]]" are [[Beast-Warrior]]-type monsters and have the same reveal requirement, while allowing for a good presence on the field and card advantage.
