I've played a bit with a HP Stall team -which is pretty similar to Kl4ng's team posted here-, and I suppose Chansey/Alomomola/Amoonguss forms a decent stallcore for HP teams. With great bulk on the opposite sites, Chansey can take special attacks while Mola deals with physical ones. Meanwhile Amoonguss resists all things the other two are weak to, namely Grass, Electric, and Fighting. On top of that, Wish and Regenerator makes these three Mons even harder to break.
Apart from Wish passing and healing status with Heal Bell, this core can also cripple opponents with Toxic, Scald burns, Spore, and even Knock Off, since Alomomola learns that.
Apart from that, HP has some other neat options:
Unaware users as in Quagsire or Clefable help keeping set-up sweepers in check, who would otherwise just set themselves up in the passiveness of the aforementioned core. (you could actually run Clear Smog on Amoonguss to keep stat boosters at bay, although I wouldn't rely solely on that)
Mew obviously has its expansive Movepool, and is one of the few hazard clearers HP teams can get. The other Mons mentioned which can Defog are Mandibuzz (most probably viable) and Skuntank (eh...)
Diggers and/or Azumarill can function with that core as well if you don't want to run full stall, being used as mid-lategame sweepers to finish off the crippled opposition, or simply to revenge-kill stuff.
CurseTalk Snorlax and CM Clefable might work as win conditions on HP teams, although I tested neither of them, so I can't really say.
