Tyranitar starts infinite sandstorm and Pursuits spinblockers, which can cause a headache for stall teams. It's been a staple of many Gen 4 stall teams, and only looks to be more popular in Gen 5, to change the weather from Rain or Sun and put a wrench in the works of Rain teams that would otherwise walk all over traditional stall teams.Because stallteams cannot run Tyranitar and Scizor reliably while the offensive opponent can run both Rankurusu and T-tar/Scizor as they work very well together.
You do realize burns halve Attack, right?All these calculations have been made against a maximum Physically invested Spiritomb
CB T-tar Crunch: 49.7% - 58.6%
CB Scizor U-turn: 42.1% - 50%
Yache SD Chomp Outrage: 44.4% - 52.3% after SD: 88.2% - 103.9%
Gliscor can set up with ease thanks to it's immunity to Burn
Life Orb Doryuuzu EQ: 49.3% - 58.2% after SD: 98% - 115.8%
Roobushin can set up with ease as well considering you actually boost it's power after a burn
Gyarados: Most common version nowadays is the taunt version to stop Nattorei, spiritomb can't touch it.
Dragonite: I'll give you this one.
LO Blaziken Flare Blitz: 54.3% - 64.1% after SD 107.9% - 127.3%
Metagross Meteor Smash: 41.8% - 49.3% -> you induce burn than you die i hope for you it doesn't have Lum berry
Lucario: I'll give you this one
LO Randorusu: 61.2% - 72% in Sandstorm
LO Cloyster Icicle Spear: 52.6% - 62.5% after Shell Break: 105.6% - 124.3%
Choice Scarf Jirachi: 25% - 29.6% -> you may win if you're lucky
I wouldn't consider a pokemon who can only reliably stop 2 out of 15 of Generation V's top physical sweepers with a maximum defensive investment to be an effective physicall wall.
CBTar does around 50% with Crunch, Spiritomb burns it, and it's basically useless for the rest of the match. Choiced versions of Garchomp are far more often used than Swords Dance versions, and Spiritomb easily burns those and Rests off the damage. Gliscor is never used as a sweeper. Roobushin can only use a 50 BP Payback to try to hurt Spiritomb, allowing Spiritomb to whittle it down with Shadow Ball while taking only 14.5%-17.1% from a +0 Payback, and still very little, even with boosts from Bulk Up. Gyarados is never used as a sweeper. Spiritomb burns Metagross and Rests off the damage.
Need I go on? The "expansive list" you provided nowhere near represents the majority of Generation 5 sweepers. I'm not trying to say that Spiritomb is a wall capable of stopping all sweepers; indeed, that's not the issue at hand. But Spiritomb is absolutely capable of stopping a significant enough portion of sweepers that it is in no way "dead weight" on a stall team besides stopping Rankurusu. Let's stop kicking this dead horse.
You do realize how Perish Song is supposed to be used, right? You don't immediately switch in and use it as Rankurusu switches in, to force it out immediately. It's meant to be used to stop a sweep by a bulky set-upper, not to be the first response to it. Anyone who uses it that way is misusing the move; if they're spamming it every time Rankurusu comes in, of course it'll lose PP quickly.I have read Obi's stall team with much interest and yes, and i admit it was an effective team during Generation IV. However that it was effective back than doesn't necessarly mean it's effective in Generation V
How is 8 PP enough? Take the fellowing scenario: starting with a Heatran-blissey matchup
Turn 1
Heatran switches out to Rankurusu
Blissey does whatever(can't hurt it anyway)
Turn 2
Blissey switches out to Celebi
Rankurusu uses Calm Mind
Turn 3
Celebi uses Perish Song
Rankurusu uses Psycho Shock
Turn 4
Celebi uses recover
Rankurusu switches out to Heatran
Turn 5
Celebi switches out to Blissey
Heatran uses whatever( can't touch blissey regardless)
Repeat this proces 8 times and the Rankurusu user wins, i've done this 3 times succesfully on the ladder. While it doesn't work in a simple proces like that in a real game it usually comes to switching in Rankurusu 8 times which is incredibly easy against a stallteam.
