DD seems to be taking over as the dominant set, with Scarf and Band dropping off a little bit. With the variation in coverage and Tera types DD Flygon can run, and now emerging bulky sets as well, it may well prove to be the tipping point for Flygon. A suspect doesn't seem out of place, and would at least serve to drive analysis on how broken Flygon actually is.
I've been asked before by stories to explain why I'm pro ban on Flygon, and I totally ignored her because I wasn't down, but now that I have time and feeling much more patriotic to the cause, I thought I'd explain.
In general, what we saw in the zS BJ match and the quoted Django post sums up how I feel. The issue with Flygon has always been set variations on its DD set. In this tier, we have very few hard checks to Flygon once it gets going and most people rely on multiple soft checks to defend against it. Examples of soft checks include and are not limited to: Haze/Ice Beam/Alluring Voice fat Waters, Sylveon, Bronzong, Toxic Gligar, Orthworm, ones own Flygon with Tera, Tera on random defensive pieces, Scarf Shao, Scarf Munki, etc etc etc.
Although it seems as if this would allow for enough flexibility in the builder, it becomes pretty clear pretty quickly that Flygon can mix up its set in a ton of different ways in order to bypass basically all of these. The only two mandatory moves are truly Dragon Dance and Earthquake and then its up to ones imagination. For example, let's say you want to go with a classic offensive DD Flygon with Scale Shot + Dice. In your last slot, you can go for Throat Chop, Fire Punch, Fire Blast, Substitute, Draco Meteor, U-Turn and probably a few other things (this is what I've personally used) in order to pick and choose your counters a bit. Teras will usually be Steel which flips half of its matchups anyways, but others like Fairy, or Ghost, Ground, and Dragon are all viable as well (I highly recommended messing around with Tera Ghost + Throat Chop to stunt on IDBP Zongs). And these are just offensive Scale Shot sets. Others like bulky Breaking Swipe (the zs special) or innovations like the bulky Sub set we saw in SCL today are both interesting and viable routes to take as well. This is before we even get into non Scale Shot sets as a whole, bulky and not bulky, with a mix of coverage, Sub, Teras, whatever. The things this mon can do are remarkable in the right hands and with smart building.
I think the reason people are hesitant to ban Flygon is because it's such a good mon for the tier in every other aspect. It's a fantastic Scarfer, CB holder, and Rocker while being a Levitating Volt immune with a strong speed tier in a Spikes meta. In reality though, this meta isn't the same as a week or two ago. We lost three good checks in Talonflame, Umbreon, and Quagsire while (deservedly) banning Cresselia, another check. At this point in time, I think we have to stop trying to hold onto the broken pieces of a past meta that was pretty good because it doesn't exist. Mons like Flygon on top of things like Mienshao, Pom-Pom, and potentially Rain, just aren't balanced as they used to be. I don't think there are unbans currently or adjustments that would make the tier better with the rises that we had and a banning of those 3 or 4 mons feels like the way to go. I know I'm not the only one who feels this way about the meta, so I'd like to invite others to speak on it as well, including our dear TL
etern since we talked about it earlier after I brought it up in the NU Discord.

- I heavily dislike this guy in the tier. In the past, Talonflame's presence in the tier provided a way to punish Mienshao, whether Scarf or Life Orb, and we had Cress to sponge hits a bit sort of not really. Now, we've lost all of that and there feels as if there's essentially no way outside of Vileplume to punish Mienshao (which can lose to Pads + Axel or just by being overwhelmed easily in this meta). Basically, no way to punish Shao + a lack of good Fight resists = an unhealthy presence to me. We have Fighting-types like Migo that can fill the role while being easier to punish as well with things like Helmet, so to me this feels like a healthy ban for the tier. Don't really think I need to elaborate on this currently because it feels way more straightforward than Flygon.

- Stupid cringe bird haxes and 1v1s everyone, beats checks with Taunt or Offensive and the combo of Tera, and is overall stupid and adds nothing positive to the tier.

- I'm currently of the position that Rain is ok, but it's something I'd want to keep an eye on. I think we've seen a pretty noticeable increase in bulky Water balances and Teraing out of a matchup to get rid of a rain mon is a pretty viable use of Tera that can neuter Rain in a lot of games. I do think that Overqwil + Basc can be pretty insane with your choice of Rain mons (Kilo, Kingdra, Ludi) and setters (Klefki, Torn, Illumise, Uxie), but it's not an individual mon issue. Either ban Damp Rock in the future or don't touch Rain. I'm currently on team do not touch. It's nice to have a cheese playstyle to keep people honest sometimes.
epic post just wanted to give it credit LOL

- Regarding Cress and its ban since I've seen some confusion over it and sentiment to unban it to help deal with Flygon and Shao: nope! There's a reason that we decided as council to ban Cress, even with some people in the community calling it C tier, namely, the builder presence on Cresselia was stupid. Cress either would 6-0 a team on preview or your opp packed 2 Cress checks + Taunt + Phasing and it was sack fodder with very little games in between. Tera + Cress shenanigans also allowed it to flip the matchup on a bunch of checks + forced certain movesets or spreads on mons like SD being mandatory on SpDef Incin. Overall, it's a weird ban if someone spent their whole time just laddering against webs HO, but it put a heavy strain on the builder in really awkward ways. Goodbye good riddance in my opinion. We shouldn't be looking to unban this because it won't solve our problems. We should get rid of the things that you want to unfree Cress for.
