>>30224340Zygarde 100% showed us anything with good boosting moves and coverage options is instant Ubers with inflated BST, even if it's attached to a horrid spread and exploitable typing. 110 flat + 115 spe is excessive to put Sylvally in Ubers because you can just run a Swords Dance set and meme all over OU.
It's not like if we removed CM, Recover, SD, ESpeed, and plate type boosts from Arceus a 720 BST monster would drop to OU. Well, maybe like Arceus-Bug would (maybe) but the idea is excessively padded stats in combination with ridiculous offensive options will break a Pokemon.
