CaP isn't as far fetched from OU as some people make it out to be. Honestly, it's a fact that stall is prevalent in CaP. However, it is dumb to say that single pokemon can take down stall. Zapdos isn't even used as a sweeper as much as the bulkier variants in CaP either. Stall requires multiple pokemon to break down. It's quite easy though, as well built offensive teams are infact the bane of stall teams. It's foolish to say one pokemon can break down an entire team, provided that they run Fidgit/Skarm/Bliss/Argho all the time.
Either way, most things that work in OU do infact work in CaP. I for one use my standard team for CaP, which works absolutely fine.
Arghonaut has also made a rise in stall. Not that Arghonaut alone makes CaP so stallish, but without it, people wouldn't have as good of a CaP stall as they do now. Of course you could single out pokemon, but the fact is that once a pokemon in stall dies, the effectiveness of the team significantly decreases.
Ok, but if CAP is by itself biased to stall, claiming that we need other bulky, wallish Pokémon or something which can help stall - as if Pokémon like Argho, Fidgit and Revenankh did not even exist - is a bit too much, don't you agree?
I also know that, much like Argho alone isn't the reason why CaP is so stall, if CAP9 would be a sweeper or a wallbreaker it would not change things that much. But, in my opinion , ti would be a step into the right direction. Certainly more than another tank like the one CAP8 is turning into.
Again, just my opinion.
