I too started using a stall team, with a Rotom-H lead (restalker of course) a Wish Bliss with ST and Flamethrower (toxic wasnt cutting it) a Swampert, a Skarmory, a Tangrowth, and Tentacruel.
The Swampert is there because I needed a good roar user, and I liked how Swampert made for a good Metagross counter with his Steel resistance. For this reason, I used him over Hippowdon. That, and I didn't want Sandstorm running because my team needs leftovers worse than my opponent does.
Tangrowth resists EQ better than anything, and helps with Gyarados. He also as Knock Off to remove my opponent's leftovers, and Leech Seed to wear down sturdier opponents. He also baits Heatran better than anything on my team (save skarm) and can Earthquake it on the switch-in, killing it.
Rotom-H is better in this metagame because he resists all of Scizor's standard attacks, so I chose him. Unlike Spiritomb, he can also take on Metagross for me. I put him in lead because he is sturdy and immune to Explosion, perfect for killing beating Suicide leads. Most teams don't have a rapid spin blocker, so Tentacruel can usually spin the rocks away anyways.
I put Toxic AND Toxic Spikes on my Tentacruel, so that I can poison Rotom switch-ins, and Gyarados switch-ins. Rapid Spin, Surf, blah blah blah.
Blissey is pretty standard, but I put in 24 HP EVs for optimal leftovers recovery, and only put in 56 SpA EVs. Then I put Seismic Toss over Toxic, just for some decent all around damage. Helps with Heatran, who expect me to be a Flamethrower/Toxic version, and then they realize they can't stay in anymore.
Skarmory is standard, but I run a hell of a lot of speed on it... something like 207 or whatever, just so I can Whirlwind Suicune before it Roars me. Drill Peck > Brave Bird, because I don't want to hurt myself too much. A few times Brave Bird killed me after tanking a hit from Heracross or something.
Thanks for writing such a good guide Obi. I tried to be as different as I could (like using togekiss to wish, and whatnot) but eventually I came crawling closer towards your top notch design.
