First time posting on Smogon so hopefully I get this one down.
I'm a bit new to PU still, but I've been having a lot of fun with this team and after a lot of revisions, it feels betters than ever at the moment. I also don't ladder as frequently as I probably should, but I still think the team is pretty cool. I'm not entirely sure what to call it, but I'll go with
Qwilfish Balance given that I set out to have a team with Qwilfish in the first place.
Paste: Qwilfish Balance
The general gameplan is pretty straightforward. Get Spikes up (not always necessary based on the matchup), and use the general defensive options of all the mons on the team to comfortably switch into anything and win most trades. While I don't have Knock Off, and have dropped any previous spin blockers and Galarticuno, the threat of Spikes still forces the opponent into awkward positions and pushes more chip in my favor.
Qwilfish was the first pokemon I made, and back when Tsareena was in the tier, was the primary thing I used it for, as a pokemon that would beat Tsareena less effectively than Weezing, but would also beat Weezing in the process. I've since dropped Poison Jab for Destiny Bond, since being able to take any pokemon down with you is so, so amazing. Taunt and a poison typing help with beating other passive mons trying to beat my team in the long game, and of course, Spikes are always nice to have. I chose Liquidation over Waterfall because I wanted to squeeze as much damage out of Qwilfish as possible, and the chance of getting a defense drop could save me an interaction in a pinch. With 96 attack EVs, I can 2HKO a Gigalith a majority of the time after a defense drop, 2HKO offensive Espeon that tried to bounce Spikes, and generally smack most physical offense threats for good damage. 120 speed and a jolly nature makes sure that I can outspeed minimum speed Espeon with a bit of wiggle room, just to make sure I can pressure opposing Wish Espeon better. The 40 defense EVs are mostly tacked on, but they do allow me to take 2 Earthquakes from a Quagsire, and generally give myself good math if I feel the need to DBond it. If you couldn't tell, this is who I put the most thought into. This gives me a nice check to Glastrier, Hitmontop, and physical Silvally forms. It also acts as a nice stop gap to things like Scyther, Weezing, Ninjask, Glastrier, and Gallade, putting good chip damage onto them at the very least, or in Weezing's case, turning it into free pressure with Spikes and/or Taunt. Combined with Sandaconda and somewhat Eldegoss, I feel prepared for most physical threats.
I think Gigalith is absolutely insane, particularly with Tsareena being gone and the new drops added into the tier. While it won't stonewall things forever, the offensive pressure it puts out, combined with sandstorm and toxic chip, feels incredible on a team like this. It almost always feels more worth it than not to trade Toxics with a Jellicent or something, and when it can so easily block most of the tier's special attackers and sweepers, like Zard, Ribombee, Galarcuno, Galvantula, and somewhat pokemon like Whimsicott and Espeon, as well as having a good typing to deal with mons like Ninjask and sort of Scyther, I think it does so much. I elected to not run Rocks on it, or anywhere on my team, because I think Protect is super important on it, but getting Rocks up is never a bad option to have.
I elected to go with Wish Espeon here, since most of the pokemon that would normally scare it, such as Ninjask, will hate staring down the pokemon it passes to, and I'm finding more and more often that Espeon's damage output is still totally serviceable. It gives a lot of longevity to the team, and bounces back annoying will-o-wisps and hazards. Sometimes I even get cheeky and switch it into a webs lead after having led Gigalith (Do not do this), which turns one of the team's bigger weaknesses (overall lower speed) into less of an issue. There's not much to say besides that it sits on Ferroseed all day since the poor thing won't heal and never does significant damage, and isn't afraid of most setters besides Druddigon and the Webs bug types. I opted for DGleam as the fourth move just because Scrafty can give this team problems sometimes, particularly when you don't know the set, though it also helps for hitting things like Absol that try to come in.
Do not put Boots on your Glastrier, you lose out on so much potential from it. AV Glastrier, when paired with Wishpeon and hazard removal, becomes an amazing physical tank capable of 1v1 several mons it has no business beating, namely Charizard. I opted to run HP investment over speed, capitalizing on bulk, but some speed could do this thing some good. Icicle Crash + HH and CC give me basically all the coverage I'd need, with Crunch adding some bigger chip damage to Jellicent, sometimes forcing it into passive positions on the defensive set, and outright nailing it on Specs sets. Please run AV Glastrier it's so much fun having this thing come in so easily and fire off big damage.
Up until recently, this was a Morpeko, with the logic being that I was a spinner that threatened Jellicent, instead of inviting it in. While I lose offense and a better Espeon matchup with Goss, I now get access to a strong spdef Regenerator mon that can provide the rest of the team healing and beat Jellicent with much less stress. This also helps me beat Sandslash much more easily, as well as generally scout against things. The fourth move could change, but I like Aromatherapy just to make sure I don't have to play perfectly around opposing status, and give myself a bit of breathing room. Otherwise I'd suggest a powder move to spread some annoying status, or Leaf Storm if you think the nuke option can help edge out a game. I wouldn't personally recommend Pollen Puff, but it could be nice for dealing with Espeon.
Finally, Sandaconda. I think it's the best physical wall right now, since Regirock and Aggron still despise status, the former hating poison chip and the latter having a lot of bad weaknesses. With Coil, this gives me a good way out from DDance Scrafty, while DGleam gives me an answer to Bulk Up Scrafty. I also keep pokemon like Lycanroc, Togedemaru, Gigalith, and Aggron from posing a major threat to me. Coil sets up for strong end game positions and gives me a way to clean up and potentially check certain setup options. Rest keeps me healthy, and Stone Edge gives me a coverage option in a pinch.
Weaknesses: This team does not have a steel type, and on occasion, you can feel that. It struggles a lot against Magneton, as well as a lot of setup options. The team can have issues into teams with much more offense too, though that might be that anyone could run 6 Choice Bands into me and I would have no hope of winning.
Sorry that this was a lot to go through, but yeah, I think the team is pretty neat. No one pokemon feels like it's taking the majority of the weight defensively, and I never feel like I'm stuck playing too passively.
