Didn't find one of these, so I guess I'll do it.

Spiritomb is an interesting pokemon. It has fantastic defenses but very low HP and no recovery outside of Pain Split. It can counter several important pokemon (Notably Reuniclus and Deoxys in Ubers) but has a hard time with many of the other OU pokemon. It has no weaknessess and three immunities but few resistances (Just Poison). It has a large support movepool and access to useful moves such as Sucker Punch and Shadow Sneak, but there's not a whole lot it can do that others can't do better. But here are a few sets.
CroTomb
Spiritomb @ Leftovers
252 HP / 252 Def / 4 SDef Bold
Pressure
--Rest
--Sleep Talk
--Calm Mind
--Dark Pulse
This is a great set that is hard to counter. With maxed out EVs, CroTomb's defense is sky high, and after a few SDef boosts, it's going to be hard to take down. The idea is to use CM until you're low on health, then to heal up and spam Sleep Talk while you boost and attack. Very hard to counter.

Band Tomb
Spiritomb @ Choice Band
252 HP / 252 Atk / 4 Def Adamant
--Trick
--Shadow Sneak
--Pursuit
--Sucker Punch
Spiritomb has a decent attacking stat and access to Trick, which makes this quite an effective set. CB Shadow Sneak hurts a lot, especially if it's STAB coming from a maxed out Atk stat. CB Pursuit also really hurts, especially if the opponent is switching out. The only problem is a really limited physical movepool, which really limits Spiritomb's attacking prowess.

Torment Tomb
Spiritomb @ Leftovers
252 HP / 128 SDef / 128 Def Impish
--Torment
--Protect
--Spite / Toxic
--Sucker Punch / Pursuit
This will make your opponent rage quit. Torment coming from a tank like this is a pain. Say for example your opponent only has a fighting move and a rock move (Terakion). You Torment the Rock move, Toxic or Spite the Fighting move, and Protect on all of the Fighting moves. Soon your opponent is left with 0 PP in both attacks and is forced to use status moves or Struggle. Or, if you chose Toxic, your opponent is dead (although they may have switched out to eliminate Toxic damage). Works great with both Sucker Punch and Pursuit. Pursuit catches them when they try to switch out and can really mess up Choiced pokemon. Sucker Punch is good because you know exactly when to use it.

Tank Tomb

252 HP / 128 Def / 128 SDef Careful
--Will-O-Wisp / Toxic / Hypnosis
--Pursuit / Shadow Sneak / Sucker Punch
--Pursuit / Shadow Sneak / Sucker Punch
--Pain Split
Just a great all around tank. Great support options, great choice of moves, and okay recovery that can hit the opponent really hard. It is possible to do 4 HP / 252 Def / 252 SDef for max Pain Split recovery, but it's not necessary.
