I'm planning on making a Gliscor soon, so thanks for sharing that last bit. But wait, what is it that's more common in stall v stall... the need to reactivate Sturdy? Or the 19 speed IVs? Also what is this about a higher HP-to-Def ratio?
As I mentioned, Timid Arceus with 112 Speed EVs lets it outspeed threats up to Jolly Garchomp while using less Speed EVs and letting Arceus focus a bit more on its bulk. Your spread outspeeds up to Rayquaza while using more Speed EVs.
