As much as i like creativity, which is definitely one of the goals of this thread, some team styles are pretty crappy for this project.
How are we going to build a Gravity, Sun Stall, or Quick Stall team, when most of the community have never played with such a team? Hell most good players (i mean tour players) have never used one of those teams, as far as i know (maybe i have heard of one SunStall team but this is all). Those teams don't even have a solid definition of what we should use and how we should use it (except from SunStall). Yeah some good players can guide discussion and help the ones that don't know to learn, but i don't think that a project such as this should be lead by 2-3 person who know what are they doing, and the others blindly following. Because if we use such teams, you can be sure that we will either follow the advice of those who know very well (the very few i talked before) or we will fail... You thought a Zoroark team was difficult to make? Well good luck OU players making a team with the single most difficult playstyle to build and use in OU, sun stall, and teams with a theme that is considered gimmick and have never seen any success into the competitive scene (if they have i am sorry, and i would like to see the RMT), Gravity and Quick Stall.
Why not go as we have in the past projects? If the community had problems building a team with one underused poke, what makes you guys think that it will handle better, not a single underused and hard to use poke, but a rare and hard as fuck to use play style? So let's not handicap ourselves, THIS IS A COMMUNITY PROJECT! It's not Ginganinja, Lavos Spawn, Pocket, and Harsha building a team (just some good players i know), it's the whole community, so let's please make this endeavor worthwhile.
If we go with a sand balance team type, like i am proposing, we will have the single most diverse type of team in the metagame. We will have the most options available. Which means that there will be plenty of space to use that one special poke that all CCAT use, and it will be possible for it to pull its weight on the team, provided we chose the right teammates. Yeah cookie-cutter sand balanced teams exist, as do cookie-cutter teams for every kind of viable team style. The fact that they exist, doesn't mean that there is no room for creativity.
Btw i didn't meant that only my choice is viable for this project. All kinds of offense (weatherles offense, Rain offense, Sun offense, Sand offense, Hail offense, bulky offense), all kinds of balance and Sand, Rain, weatherless semi-stall are viable and could give us good results. Note that i believe that only semi-stall would be vaible, because hard stall is very hard to play and to use (not saying it is impossible), so it won't go so well. But semi-stall can have a taste of offense, so it will appeal more to the people, as well as being closest to what they know to build and play.
