I've been hovering around #1 for a while now (every once in a while Swagilyph attempts to wrestle it away from me :/) by using Stall and here are my impressions:
-The Spinners and defoggers in this tier are unbelievably ass. I literally went without a spinner on a stall team because I felt like I would get more mileage out of just running something thats actually going to win games rather than crippling my team to save some percent. As of so far, sticky web has been more of a threat to my team than Spikes and SR in terms of pressure, mostly because there's some things (like Marowak!) that are slow as molasses but hit really damned hard.
-Sneasel is probably a necessary evil for the meta. I really can't imagine what this tier would look like without it, and with Gourg-S probly being an A+ threat, it really needs to be around to kill the damn thing. It's not really that hard to counter if you're willing to make your team worse to beat it, but it's still threatening enough to where you can't mindlessly use some of the bulky mons that lose to it.
-Musharna is a fucking boss, but this point has been discussed fairly heavily in the last page already.
-Theres been a lot of discussion on how Poliwrath is a good mon without Sneasel around. TBH, no, it really isn't. If Sneasel wasn't around I'd drop it for something thats more relevant vs the meta. It just feels like a dead mon on a stall team, but you pretty much need it as you need something that can come in on sneasel multiple times without fail. It doesn't do well on offense anymore either since Gourg ends it.
-More people need to run Fire Blast Tauros. It's just too relevant now to skip. Drop Rock Slide or something, do you really need it?
-Licki is, as expected, a stall staple. It plays out exactly as anyone would imagine it does. Its also great support for Musharna so they can afford to run Dazzling Gleam, with Licki having Heal Bell.
-I hate using Garbodor, he's literally trash. But hey, at least he's a pretty good spiker, just wish he got Knock Off.
-Marowak really needs to have a real counter in this tier. Like. REALLY. Why does this thing learn Knock Off, that's not even fair.
-From an outside view, I'm guessing the prelim rankings were based on last month PU? It's just that most of like A through B+ is like flipped upside down now lol.
-I ran into a single Quilladin on the ladder, and it carried their entire team. That thing is a monster, probably the most underrated Pokemon in the entire meta. It gets Spikes, Taunt, is kinda fast (faster than a lot of other stall mons, and you have some room to creep), and just doesn't die. Not a whole lot of things can kill this, and out of them, Simisear is probably the only one that isn't piss easy to wall with other stallmons. Potentially a better Pokemon than Gourgeist if the meta shifts to something more defensive after the recent tier changes, and Gourg is already one of the best mons in the meta. Pair this thing with Haunter and/or Spinner and you basically cannot lose to a stall team. It's still a bulky grass with spikes vs offense and balance, so its not dead vs those teams either. Grats to whoever figured this monster out.
