Is Exodia Millenium the new runick stun?

I thought it was only used during the event, but the master is infested with this thing. And it's unbearable to face, because it's always full of floodgates in the main deck. The fiendsmith meta is bad enough. And we still have to put up with this annoying thing? Man, this meta is getting more and more unplayable. What a miserable gaming experience.
