>>86665750Pokemon's equivalent of Mumei is Pidgeot from FRLG, which was so powerful, that Pokemon released a bunch of ability blockers as damage control. it got revived on a recent set as Pidgeot ex, but the meta nowadays is so different that it isn't as overpowered as before.
tl;dr powercreep will make Mumei obsolete and more degenrate cards will come out in the future
