'Tis an epic stall team I came up with by accident.
Enjoy and critique please!
Pictures for the newly added Pokemon coming later today!

Just got a 4 Pokemon sweep with Swampert!

Swampert @ Leftovers
Torrent
Relaxed
240 Hp, 216 Def, 52 SDef
Earthquake
Ice Beam
Stealth Rock
Roar
This is my lead and Phazer numero uno. I usually go out, set up rocks, Phaze/get out. On occasion I'll catch a napping Tyranitar that wants to take me out with a nice Earthquake. Not many leads actually want to put up with Swampert, I've come to find, so the rocks usually come free. It also puts a fear in the hearts of some, and they hesitate on bringing out Garchomp.


Forretress @ Leftovers
Sturdy
Impish
252 Hp, 252 Def, 4 SDef
Spikes
Toxic Spikes
Rapid Spin
Payback
Oh yeah! This thing can setup like no other. after Swampert gets out rocks, this thing can come in on most of its (Swampert's) counters, and just start laying out the Spikes. I try to keep this thing alive as long as possible, especially if the opponent has Stealth Rock or Spikes somewhere. The only part I'm not sure on is Payback. Maybe ditch it for Rest?

Gyarados @ Leftovers
Intimidate
Impish
248 Hp, 252 Def, 8 SDef
Waterfall
Roar
Rest
Sleep Talk
Bye-Bye Dragonite, you will be missed. This thing is so much better! With RetTalk it has AMAZING longevity. Intimidate was what really sold me though. It cuts the attack of anything, which just adds to the stall and forces even more switches! I am aware that it can learn Dragon Tail, and that many people prefer it over Roar, but I like Roar. It may not do any damage, but Roar can go through subs! The things role? Beastly Phazer.

Chansey @ Eviolite
Natural Cure
Bold
252 Hp, 252 Def, 4 SDef
Aromatherapy
Toxic
Softboiled
Protect
Bringing back the new and improved Chansey! Serves as a special, or anything really, wall. Eviolite makes its defenses better than Blissey's, and using Softboiled over Wish lets it heal up quickly. This is a must, because it doesn't have leftovers. Aromatherapy is a great help to the team. Statuses on things are not good for stall teams, come to find out, and with the two RestTalkers, it can come in extra handy!

Spiritomb @ Leftovers
Pressure
Bold/Careful (can't remember)
248 Hp, 252 Def, 8 SDef
Shadow Ball
HP Fire
Rest
Sleep Talk
Since they made the Rotoms non-ghost this generation, I needed a new spin blocker. Enter Spiritomb! This guy can take a large number of hits, and once again, with RestTalk, can last a very very long time. I chose HP Fire over WoW, because I wanted a second attacking move for Sleep Talk. Shadow Ball is a given though. This thing bends Reuniclus over and just pounds away with its Lol Stick. Also, it has no weknesses. I can switch in on anything!

Tyranitar @ Choice Scarf
Sand Strream
Jolly
4 Hp, 252 Atk, 252 Spe
Super Power
Crunch
Stone Edge
Pursuit
Testing out Hydreigon to replace this, as it packs a much larger punch and is fast with scarf. The main selling point on T-Tar for me is Pursuit, and that just doesn't seem to be able to justify it over the dragon, so we shall see. In the meantime, it's a solid insurance for the team.
THREATS
Blissey - Sometimes, I just cant find the means to take this thing down. With either Tyranitar or Hydreigon, I should be able to handle it though.
Cloyster - If I don't get out Tyranitar or Hydreigon on the first Shell Smash, this could really hurt my team! Thank God for Stealth Rock though.
