Don't waste this guys attack stat, instead of Toxic, go for Power Whip!
This boy doesn't need Vacuum Wave, give him Roost so he can heal himself, and give him Bug Bite instead of X-Scissor, Technician makes Bug Bite more powerful, and Bug bite can steal berries :]
Consider defensive Ev's since he's using Bullet Punch and doesn't have that great of speed.
Water Pulse should be taken out for Dark Pulse, and Flash cannon for Nasty plot.
Go Adamant instead of Brave, with 70 Base speed, he can still outspeed a hand full of things.
Switch out Ariel Ace for Ice Punch.
You have Defiant ( Raises Attack if any stat is lowered ) and Cell Battery ( Raises Attack if hit by an Electric move ) And you're using a Special Attacker.
Change the ability to Torrent, and forget using Cell Battery, Try Life orb.
Change nature to Modest or Timid.
I like this guy, but he needs to go.
Your team desperately needs some kind of fire protection.
Get a Heatran
Heatran (M) @ Leftovers
Trait: Flash Fire
EVs: 252 Def / 4 SAtk / 252 SDef
Modest Nature (+SAtk, -Atk)
- Fire Blast
- Earth Power
- Dragon Pulse
- Hidden Power [Grass]
Fire Blast works better than Flamethrower due to PO making those kind of moves hit a bunch.
Earthpower gets great coverage, Dragon Pulse takes out Dragons, HP Grass takes care of most all of his weaknesses! He has the ability Flash Fire meaning Fire moves won't even touch him, with good Prediction he can be the All-Star of your team!
