Alright, I guess I have some defending to do. ^_^
Well, this would be an alright concept but what about the predictable CAP6/Blissey walling combo. Though I guess the whole typing thing would need to be discussed first. But it's a good concept never the less.
I could see this working maybe if it shared common weaknesses / counters to Blissey so it there wouldn't be CAP6/Blissey in every team. Then again if they both had a common counter the metagame could overcentralise to that counter...just something to dwell on. I'm tired, so sleepy time for me now.
This is obviously where the community would have to put their heads together. I'm actually incredibly interested in how we can make this Pokemon good, and do its job, but without being able to break the Blissey/CAP6 walling combo.
I personally believe that having one of the allready available physical walls plus a few resistances is more then enough to stop most of the physical attackers.
Of course this is true... A team that is built in order to deal with the physical attackers of OU is obviously going to be able to beat the physical attackers of OU... I don't see what you're trying to prove. While physical attackers aren't breaking the metagame anytime soon, but it's very obvious that they are the more dominant force when compared to their special attacking counterparts. Not to mention that it is impossible to cover the majority (not even close) of them without heavy investment in certain Pokemon. Have you ever had this go through your mind? "Well, shit... I'd like to fit 'X' into the team... but I need a Rock resist... a Fighting resist... and a Bug / Steel resist... *sigh* I guess I'll just go with 'the usual'"
I know I have. I think that people get offset by Blissey because it's fairly annoying to get through, but I think that people forget what Blissey allows us to do. Blissey is a rediculously decentralizing force. It allows for "one stop shopping" to the majority of brute force special attackers. It actually allows for MORE diverse team building because now you don't have to dedicate half of your team to taking down special attackers.
I strongly support the "Physical Blissey" Idea. Looking at the base stats of the current physical walls, such as Skarmory, with 65 HP and 140 Def; Forretress, with 75 HP and 140 Def; Hippowdon, with 108 HP and 118 Def; etc....
Of course, they have tons of immunities to back up. However, there is no such insane pokemon like Blissey (though it never gets to Uber), which has 255 HP and 135 SpD. It has actually the ability to survive a +4 Tri Attack from Porygon-Z.
Not to mention, those other physical walls can actually do_something in the meantime other than just wall things. Blissey can't really (with the exception of setting up Stealth Rock, but what can't these days?).
------------------
I envision CAP 6 to be very "splashable" in any team. If your team has significant trouble handling physical threats, CAP 6 will fit your 6th slot nicely, much like Blissey to be honest, however it should JUST do what it's supposed to do... handle physical threats. It doesn't need to support, it doesn't need to attack (beyond what is necessary to take down the majority of physical attackers). It just needs to do its job.
With a new Physical wall, we allow our teams to be more diverse on the whole.
Also, both Stall and Offense gain something in this, it's not all to one side. Stall obviously gains a new toy for its team, but Offense gains something that can take a few hits and provide a pivot Pokemon (one that you switch to in transition to one of your other Pokemon).
I can't think of anything other than a Pokemon that deftly counters the entire metagame that would be more benificial to the current world of Pokemon.
