And Jolly Weaviles are probably better overall than Adamant, just because of the boost in Speed it needs to keep up with Swellows and Jolly Pokemon from base 120 Group.[/quote]
I always seem to be disagreeing with you XD
With Weavile's Base speed as high as it is, I'd say to go with an adamant nature; the extra attack is nicer in my opinion. If Weavile doesn't get the kill in, it's as good as dead.
Also, everything in the speed range you mentioned is weak to Ice except for Alakazam, Jolteon and Mewtwo. So if you're worried about speed too much, throw Ice Shard on in compound with Ice Punch.
Weavile @ Muscle Band [liechi berry if you think you can pull off the activation by switching into an attack]
Adamant Nature
-Ice Punch
-Ice Shard
-Night Slash
-Brick Break
However, getting Ice Shard will involve breeding a new Sneasel.
Using two attacks of the same type, one being physical and the other special, balances it out a bit. Even if in most nearly all cases, there is a better option..
And for a better option, I would suggest:
Salamence@ Wide Lens / Expert Belt / Life Orb
Neutral/Hasty/Naive Nature
-Dragon Claw
-Fly
-Flamethrower
-Earthquake/Hydro Pump
Dragon Claw for basic STAB at a power of 120
Fly for the bait and trap I've come to love, and STAB as well in this case.
Flamethrower will cover any steels that switch in, and hit nicely in their lack of special defense [except Bronzong]. Will also hit nicely on anything with particularly low special defense if you have nothing Super Effective.
Earthquake Hits rock and electric types, though Electric types pose the threat of being faster and Thunder Waving you, meanwhile Rock Types have really high Defense and are likely to live.
Hydro Pump a bit innacurate and can't hit Electric types [which again, you might not get the chance to anyway] But will completely finish most Rock Types that are actually in use.
the full physical set with Dragon Dance that Fachion mentioned will work excellently as well.
You could jump the leftovers from Espeon over to Milotic.
Milotic @ Leftovers
Bold or Modest nature [Bold will take some really high-quality poffins to evolve]
-Water Pulse
-Ice Beam
-Dragon Pulse
-Recover
Since Milotic will be taking hits, I like Water Pulse for the confusion chance. Confusion can help recover come out successfully, but shouldn't be relied on.
Crobat @ Black Sludge
Jolly/Timid Nature [Depending on your attack]
-Confuse Ray
-Toxic
-Protect/Haze
-Air Slash/Bite [or Even U-Turn]
Yes it is walled entirely by Steel XD
Confuse ray to kill half of their chance at attacking you, and then Toxic. You can start playing games between Protect and Flinch as you like now, but don't always do it back and forth or they'll just switch on you if they hadn't already.
U-Turn will allow you to status and then switch to something like your Milotic to absorb hits until they die. U-Turn will also take a substantial chunk out of Psychic types.
