He is my Special Sweeper, I think. He uses Hail to buffet the opponent,Shadow Claw for Ghost types, Brick Break for anyone else, except for the types it is weak to. Blizzard is to take advantage of Hail.
Yes, he is a Sneasel. But I cant find the Razor Claw to evolve him into Weavile. That is why I only battle Lv 100.
He is Level 59.
Spinda's Thrash is a good use of its ability. Smart. But, all of your Gengar's moves (with the exception of Thunderbolt) relies on Hypnosis. Bad bad bad bad. Hypnosis has horrible accuracy and the Sleep condition only lasts for a few turns, so when they wake up, you'll have to use Hypnosis again and just hope it hits. Replace Dream Eater and Nightmare for worthwhile moves of the same type.
You can find a Razor Claw in Victory road. Otherwise, keep your Sneasel out of the action, as it is weak in comparison to others. Also, if you're not going to have an Ice type team, you can leave out Hail, as once Sneasel enevitably faints, your oters will have to contend with that nuisance as well as your opponent.
Your Pidgeot's moveset is OK, but there are better Flying types out there.
I would recommend teaching Charizard Brick Break for Doubly super-effective Rock types.
An OK team.
Looking good, though there's a few little things I want to suggest:
First off, I dont think teaching solarbeam to charizard is the best idea, as the time delay can be fatal, especially if you're against a water pokemon!
Like the thrash idea for spinda - smart and effective.
For pidgeot, I would replace mirror move or twister with a powerful flying move - either arial ace of brave bird will do.
Lie the thunder fang move for steelix, but to get rid of rock types that could use ground moves against you I would suggest earthquake. This move can also deal with fire types.
Like the gengar, but I don't think you need both nightmare and dream eater. I would replace one with a good ghost or psychic move - shadow ball is usually a good one to go with.
I'm gonna assume that sneasel is just weavile with the same moveset :) I like the moveset, but I dont think you're utilisng weavile's strong speed stats. A move like fake out or attach a poison/flame orb and have it use fling to cause a drain on the foe.
Overall, I think you've got the right idea here. Just a few small kinks to work out. Keep up the training :)
