LeadTank
Skuntank@Leftovers/Lum Berry
Ability: Aftermath
Nature: Jolly
Lead EV's: 196Att/168SpD/144Spe (144 Spe guarantees that you outrun neutral defensive leads such as cloyster (neutral nature = 239 spe, with these EV's you get 240 Spe) and Att EV lets you 3HKO Uxie (first taunt it) then Crunch it to death. Crunch/SP lets you always 2HKO Ambipom, I would first Protect because of Fake Out, after that, SP/Crunch away, because Ambipom's return is not an OHKO on Skuntank). Remember, this is PURE LEAD, so, Taunt/Protect, then Crunch/SP away and if you still have HP left at the end, BOOMM!!! Explosion.
Lead (Outside) EV's: 4HP/252Att/252Spe This one here, is also for the lead, just use the same moveset, but here you can come in later on the game. Though you have to switch out from Moltres otherwise you get OHKO'd, and you take more damage from Omastar/Cloyster, but you can atleast come back later on in the game and explode on things like a Venusaur who otherwise would rip your team apart.
Moves:
-Taunt
-Crunch/Pursuit/Sucker Punch
-Protect/Sucker Punch
-Explosion
Explanation: I use this moveset on one of my teams, it's great, and it's crap at the same time. Its great for slow/neutral leads such as Cloyster and Omastar and every lead who's slower than 240 Skuntank (neutral Cloyster gets 239 Spe). With it's average 93 Att boosted with 196 Att EV's, can it deal some pretty well damage. With it's 103 HP it survives sometimes even a EQ, even though I have only seen that 2-3 times. It's a shame that his Def is only 67 and its SpD is only 61, and thus not really a good lead. But with the investment in Att/SpD/Spe in the good place, you should be able to KO some Pokémon, atleast I can. When you're facing a Persian or an Ambipom, it's now simpel, just Protect from the Fake Out and Taunt or Crunch/SP away. Crunch or Pursuit or SP is your own choice, Crunch for more STAB'd Damage, but Pursuit if you think after a Taunt he's switching out so you use Pursuit to give him a Base (without STAB) 80 damage move right in his face, expecting the opponent to be atleast neutral against Dark, it's of course better if the other one forgot that Ghost is weak against dark and thus giving him a x2 Base 80 Base damage Pursuit in his face. And of course, Explosion, I love that move, even if you just Pursuit a +252 Def Cloyster (which a friend of mine has) you can take it out. Also, if you didn't guessed it by now, Jolly for +Spe so Skuntank can outrun some neutral defensive leads. Aftermath if you don't manage to pull of that Explosion, then just hope your opponent is using something like Ice Punch (I don't know) so you deal atleast those maybe hard needed damage. And Leftovers for extra health regain, and Lum Berry because I faced some battlers who were trying to status my Skuntank, and if you just get paralyzed when you want to explode, and you get that 3 times, and you can't pull it off, and you're dead after those 3 times, you feel really screwed. That's why Lum Berry is also a good choice.
Well, I think that covers up the most thinks. Tell me what you guys think!
