Just to comment about Skuntank, I have gotten a Musharna (maximum physical bulk) out of Skuntank's madness with about 75% of my health remaining. It took a lot of prediction to do it though - I had to stay in and use Signal Beam while he though I was going to switch out, and he used Pursuit for a net loss of about 25% of my health after Leftovers. I had to keep switching from Moonlight to Signal Beam so then I could convince my opponent to use either Crunch or Pursuit. Even then, I had to use Signal Beam to go for the confusion hax, which worked so I was able to use Moonlight before he could Taunt again. Eventually, I used Moonlight, he used Pursuit, I switched out and he used Crunch, making me get away. I don't remember it completey, but it went something like that.
Barring rare exceptions like that one, however, Skuntank is almost a foolproof Pokemon at doing its role. 90% of the time it will defeat its opponent, and all Psychic-types will pretty much lose against it unless the opponent gets really lucky with the predictions. It is much bulkier than Absol, and still has enough power to defeat most Psychic types which are generally extremely frail to being with. Its pretty easy to use and even easier to fit onto a team, which is overall just great - it rarely doesn't succeed at doing its job.
