I've been thinking long and hard about this for a little while now, and I want to offer up my two cents on the formats. I think my biggest and hottest take is that the 2 formats should be standard SV (tera preview). The newest format, in my opinion is always the most important because it allows for new, break-out talent to shine. It's also the easiest format to get into and the meta is always changing especially compared to later gens, which I'm sure most of you have joked about them being "solved." As I'll argue later, I think we should add older gens instead, but adding two more SV's is probably the best option imo because we only have so much time with SV as the current gen format, and everyone will be hungry to prove their salt in the current metagame, even if they do play the older ones.
If I had to give my own take of what I would want the two formats should be, it should be 1 ORAS 1 SWSH. ORAS, especially ORAS Draft, in my opinion is draft at the highest level. Everything about that metagame is conducive to a good time. Games are always a good length; team structure is perfect is open-ended, with a lot of balance thriving but room for stall and hyper-offense to thrive; and ORAS feels like pure skill is always rewarded in the tier, something I can't say about say tera in SV or even like Z moves in USUM (though that may be a bad take of mine). ORAS is just a sugar rush for me, and even though it's decently solved, it doesn't matter because every match is fun. As for SWSH, I think it's the most beginner friendly draft. Players aren't punished like they are by say hazards in previous gens (with the addition of HDB). They also don't need to worry about Z moves and megas. On top of that, the pokemon in this meta are easy to understand. Zeraora, Tapu Koko, and Spectrier offer unmatched speed tiers that balance out teams nicely; Melmetal, Buzzwole, and Zapdos provide a lot of new dimension by being bulky breakers; Torn, Glowking, and Rillaboom provide clear, valuable support options while being versatile enough to change up sets between say pure support or set-up sweepers. Personally, I feel comfortable enough to give a player of any skill level a brief rundown of SWSH and pokemon and how it works and I think they would have a fun time, and that's something I value in a metagame.
If there's some metagames I wouldn't mind seeing, but don't necessarily want, it's ADV and LT/LC. Adding in a LT/LC option would round out the year nicely, with them both being C-tier tournaments, but I can't say I like watching or playing the metagame myself. As for ADV, ADV is hype as all else, but it's skillset is just so far off from what the other gens bring to the table that I don't want it. But if you've never seen Emerald Open or an ADV draft before, it's super cool and really fun to watch. (Shout-out to Jeroni, my goat.)
The metagames I really just don't want to see is VGC/DOU. I don't want to dog on these formats, they are very valuable and offer a cool, new perspective on the game and how to play, it's just not one I care about. Don't really have anything else to say here without being too mean. (I actually think I was already pretty mean to it as is).
The other metagames not mentioned, I have no opinion towards, if they're added, I'll likely skip watching the replays, unless I want to watch a player in it. And yeah, that's my opinion. I don't know, not really too sure how to end this off. Best of luck organizers trying to get any cohesive ideas out of this, good luck to all future captains and players. I'm really looking forward to this team tour, it's probably going to be a must watch event for me this year, and I want it to be a good one. Just really excited, draft is in a good place right now and we're in good hands here. <3 <3
