Yeah, Attack especially is everywhere- and they're all pretty samey, stuff like Kyu-B, Excadrill, Ttar and almost always Manaphy in there. It could probably use some addressing, I think Exca and Manaphy are the main issues.
I've only been using spdef stall and its been really successful. There seems to be a perception that it struggles with Attack, but honestly I'd say it has a pretty great matchup, since people forget that spdef has access to defensive behemoths like Cresselia, Umbreon and Suicune, while simultaneously having a really good Manaphy check with Mega Venu. Honestly, I almost always struggle more with SpAttk which is more likely to carry difficult stallbreakers like CM mons.
