As a result of two unanimous council votes,
Lucarionite Z and Malamarite have been banned from Mix and Mega
It seemed very likely from the moment the stat and abilities were revealed, but after having given it a few days it's obvious that they are simply too strong for the mix and mega metagame. We're keeping an eye on some other stones, particularly Zygardite, but thus far the presence of these two stones has been sufficiently strong that it's difficult to determine the impact of other options.
Tagging dhelmise to implement.
