With the removal of Garchomp I'm finding a lot of tactics that are becoming more viable and old favorites of mine that went in the trash due to chomp simply being too overwhelmingly strong are easier to use, team is mostly meant to stall while my other team was more balanced, I haven't tried a good stall team since the advent of yachechomp though so I figure it might be fun to do again:
Swampert, Relaxed nature, 240hp/216def/52sp. atk @ leftovers
Surf
Earthquake
Stealth Rock
Roar
Somewhat standard mixpert, mostly used as a lead for stealth rock. Also packs enough punch to threaten speed taunters. If he survives lead role, he comes back later in the game as a ttar/heatran counter. I went with roar over ice beam so I don't get fucked by setups, most of the leads out there who fear ice beam aren't ones that pert wants to stay in on anyways.
Porygon2, Modest nature, 240hp/164def/12sp. atk/92sp. def @ Leftovers
Discharge
Ice Beam
Hidden Power (Ground)
Recover
Somewhat standard PG2. He's beastly in the chompless metagame, with trace he can counter quite a few threats. HP ground is mostly for Magnezone and Heatran, with Discharge there for paralysis. Gyarados is terrified of taking any electric attack so the slightly lowered power is of little concern, as it makes it more effective against a stalling Vaporeon.
Weezing, Bold nature, 252hp/252def/4sp. atk @ Black Sludge
Fire Blast
Thunder Bolt
Will-O-Wisp
Pain Split
Weezing is really a great physical wall, he is similar to Gliscor in his role, countering Lucario and Heracross but without that really ugly x4 ice weakness. Gliscor has better recovery but Weezing also threatens Gyarados and Weavile. Will-O-Wisp is just there to be a pain in the ass, if he hits a physical pokemon with it they are pretty much useless unless the enemy is running heal bell, which isn't that common in OU.
Celebi, Bold nature, 252hp/220def/36spe @ Leftovers
Grass Knot
Leech Seed
Recover
Heal Bell/Thunder Wave
Undecided on last slot, but Celebi + Weezing is about as solid as a physical walling combination gets without Chomp around. Celebi has the psychic resist and good recovery that Weezing lacks, while still being resistant to fighting. On the other hand, Weezing does not have all of those terrible weaknesses that make her unable to handle threats like Heracross and LO gyarados.
Tentacruel, Calm nature, 204hp/96sp. atk/172sp. def/36spe @ Black Sludge
Rapid Spin
Toxic Spikes
Surf
Ice Beam
Standard supporting Tentacruel, spins, spikes, absorbs enemy tspikes that otherwise anally rape a stall team if I don't pick heal bell on celebi.
Blissey, Calm nature 252def/80sp. atk/176sp. def @ Leftovers
Wish
Softboiled/Protect
Ice Beam
Seismic Toss/Thunder Wave
Blah blah blah this is blissey. I'd hope you know what this does by now. Wish supports the team, helping several defensive members without reliable recovery (or without recovery at all in the case of pert/tenta), ice beam is still a strong attacking option, heavily damaging attempted dragonite or salamence tomfoolery. Seismic toss would be to stop stuff like cm raikou from raping me, while twave is just a great move because paralysis is painful.
I almost want to say that an anti spinner Dusknoir would be a good idea here but it's difficult to do without opening up a hole somewhere or losing rocks, which is almost worse.
