I told you I'd be active, and I will be.
I've got some fairly different opinions than other people itt.
Weatherless quickstall is a good bet. It is perhaps the epitome of unexplored on many levels in the BW2 metagame, with stall often being defined as impossible, which I firmly believe is complete ignorance, as stall is still and extremely consistent playstyle if done correctly. Weatherless is similar, especially with weather being so dominant and the thought when teambuilding often being "what weather do I want?" Current teambuilding is centered around offense and weather, with little thought being made outside of these, therefore weatherless quickstall is an excellent choice. In addition, many of the Pokemon that could find a home on a quickstall team might be misconstrued for inferior Pokemon on other teams. There is a lot of freedom when teambuilding and almost every Pokemon on the team will be underrated. Something I'm seeing a lot of is people not knowing how to define quickstall. Someone (bubbly I think) has the right idea.
Quickstall - a form of stall where entry hazards are set up early-game and then abused through risky, fast-paced Pokemon such as SubDisable Gengar and SubToxic Gliscor. Such teams could be described as functioning with an offensive tempo but possessing a stallish nature, having somewhat of the same reliability of stall as well.
There, you can all vote for it now.
Some opinions on other playstyles talked about:
I'm going to begin with full stall. The main issue here is that people don't like stall for the most part. Stall is difficult to play for many, with most people generally wanting the fast tempo that comes with an offensive team and the joy that comes with sweeping with some badass Pokemon. I mean come on, who doesn't enjoy surprising walls, predicting and KOing switch-ins, et cetera. A full stall team would, I guarantee you, turn out generic, boring, and generally lack participation. While full stall is definitely a viable playstyle, it just is not ideal for CCAT.
I personally don't lime the idea of sand/rain/weatherless balance. Such teams already have heavily defined roles and members throughout the course of the BW1 and BW2 metagames. These teams are so ridiculously easy to make that it is not even funny. Do you have walls? Do you have hazards and offensive pokes? Okay synergy? That's a balance team. If that doesn't scream boring to you, then I don't know what will. Obviously I'm oversimplifying, as we COULD make fun and unique balance, I just feel that it's too easy, too simple, too defined to be a CCAT that is a learning experience.
Now on to dual weather. I kind of get it. I really do. I just think that this would turn out too cookie-cutter of we don't restrict it enough. Here's the deal. No rain + sand and this concept could succeed. I like the ideas of rain + sun, sand + sun, sun + hail, sand + hail, and rain + hail, but rain + sand is literally THE dual weather if you want to go that route for whatever reason. Dual weather is fun to play and fairly unique, but it loses its uniqueness of we go rain and sun.
Sun stall sounds neat. When you think of sun stall, what do you think of? Before reading recent posts in metagame discussion, I thought "lol noob strategy" almost immediately. Most of you probably felt the same way. This is for numerous reasons, mainly that Ninetales is horrible and sun is harmful to staples of stall teams, Steel-types. However, underrated Pokemon such as Cresselia can shine on sun stall, which is really cool, and we probably won't have much Genesect, the new bane of stall, trouble thanks to Ninetales and the possible Heatran, which is a huge draw. I still think that it may be a little boring, similar to full stall, but it's so unexplored that it shouldn't really matter.
Now that stall topics have been taken care of, I'm going to take the liberty of moving on to offensive playstyles. The first thing I saw was rain offense, to which I say come on, be creative! Rain offense is probably the single most explored playstyle in BW2. We want an unexplored playstyle, not standard. On the other hand, Rain Dance offense could be fun. However, since I strongly feel that CCAT should be a challenge, that it should not be allowed to include Kingdra. Kingdra is the premier and sometimes only used sweeper of Rain Dance teams, creativity is key. Ludicolo, Kabutops, Floatzel, let's try something new!
Next topic of offense is hail offense. I like this sort of team for one reason and one reason only: we would get to test out SubRoost Kyurem with Blizzard. That's something I've seen fairly heavy interest in, and I think our CCAT could turn out to be the culmination of everything tested and optimized for SubRoost Kyurem by going hail offense. This would get good participation from the people we WANT participating. Most people cannot construct a well-built hail offense team, and a hail offense CCAT could teach people how to properly do so and garner interest in the strategy, increasing the popularity and relevance of this extremely underrated playstyle. So yeah, I like hail offense.
I'm going to lump Trick Room and Gravity together and regurgitate what others have already said. These strategies are going to give us an inferior team if we pick them right away. Basing a team around Trick Room is extraordinarily difficult to pull of and imho not worth the effort. While I am slightly more convinced by Gravity, I still think that it will have us end up with an inferior team. I originally was thinking of a 2 FEAR no Riolu team, but it falls under this category on the fine line between viable and not viable.
Before I move on to another topic, I'd like to bring up one of my own ideas: dual screens heavy offense, albeit with one restriction. That's right, I want us to make a dual screens HO team without Deoxys-D and to explore other options for dual screeners. My reasoning is as follows: Deoxys-D is the standard and pretty much only used dual screener. My personal vision for this CCAT is something obscure and creative yet still effective, so finding a different dual screener with a solid niche would be a requirement for a dual screens heavy offense team.
Okay, I'm going to wrap up this post with a bit about your process. It's pretty good, but I suggest two things:
For one, I suggest restricting more common and defined playstyles from their biggest, most threatening guy on the block. This allows us to learn more from CCAT and to not just create some bog-standard team, which I have emphasized upon many times throughout this post. There isn't much else to say on this subject; it's a suggestion, take it or leave it.
The second and last thing to note is that while it may have seemed a cool incentive in your head, abolish the vote winners' bonus. It may encourage people to join and contribute from the beginning, but it has another unintended side effect: it turns off people from joining in the middle of the CCAT. When you've got people who have votes that count for more than yours', you feel as though your say doesn't mean much when you've got these people with 50% more powerful votes. These people should be able to convince others to agree with their viewpoint if it is valid and should not needed more-weighted votes to do so. Abolish this bonus and you will be better off.
That's my two cents on the playstyles we should go for on this CCAT. Electrolye, drop me a VM or catch me on IRC if you have any questions.
I will be watching and participating itt often. Electrolyte, tú es chido. That will be all.
