I said arceus as a whole is uncounterable. Arceus can run some unorthodox move to bypass said counter/check. Arceus has an easier time sweeping late game due to its access to priority that other mons can't hope to compete with. I would argue about how you're wrong in that arceus normal provides no synergy but that would involve blitzlefan coming in here and bitching at me which I want to avoid.
This is why I avoid this thread because of the blatant, unchecked stupidity that seems to run rampant here.
