About OU Celesteela analysis.
The Overview sounds misleading to me from the start. Is this based on early SM metagame? Celesteela has fallen far from its title as the best blanket checking-wall. Kartana gaining Knock Off, increased usage of Heatran, Magnezone, and the worst, Zygarde are all detrimental to this Pokémon's viability. I will assume Celesteela's "well-rounded stats, and a large movepool" contributed to its versatility in early SM generation. However, there are more misinformed sentences even if we keep this in mind.
How does Celesteela snowball in the first place if its mediocre-at-best offensive stats force it to run Z-Crystal and Celesteela itself has to grab a KO? Any Celesteela lacking Leftovers will obviously give anyone a sense that Celesteela is running something else, especially if it turns out it lacks Leech Seed. The sentence itself admits that Celesteela lacks potential as a snowball sweeper, but why is this minor information even mentioned in the Overview? I believe Other Options is sufficient for this point. This has a decent chance to make readers believe that Celesteela can viably function as a snow ball sweeper, and this is definitely not true (accounting on mediocre power, moveslot syndrome when attempting to run offensive sets, and inability to hit the most common Pokemon like Landorus-T, Heatran, or Toxapex in one moveslot).
I would rather not CMS the Overview because I am not the most knowledgeable in OU and it would rather be better for a QC member of someone with similar level of knowledge to rewrite the Overview itself. I may be incorrect, and if so, please tell me why that's the case.
