I suggest that you trash that team and start from scratch. There's a lot of things wrong with your team and your view on EV training. I'll point out a few here:
1. EVs are gained every time experience is gained during battle and any given Pokemon can have only 510 EVs total. Considering that your Weavile is lv. 70, it would've reached that cap long ago and isn't gaining any more EVs (unless you used the EV reducing berries; Pomeg through Tamato).
2. Levels are pointless... for team rating anyway. With Gen IV's wi-fi having a feature that lets your Pokemon be lv. 100 for a wi-fi battle and battle simulation programs like shoddybattle, listing levels are completely trivial.
3. Stats don't need to be listed. Team raters can get a pretty good idea of your stats from the Pokemon itself and the EV spread it uses.
4.
Learn about the positive (and negative) effects of the different natures.
5. Move redundancy is redundant. There's very,
very little reason a Pokemon should have two attacking moves of the same type. Having two moves of the same type restricts your type coverage. One will do a more efficient job than the other and that move should be used over the other one. That way, you're not wasting a move. For example: Choosing between Thunderbolt and Discharge. Obviously, Thunderbolt is more powerful than Discharge and all Discharge has is the
slightly better possibility to give the opponent a status condition. Thunderbolt is the obvious better choice.
6. HM Moves Suck. Only exceptions are Surf and Waterfall. Need to get around? Just stick them on Pokemon you don't use. See 5.
7. Make your moves compliment your Pokemon. You have a high attack Pokemon like Weavile and you're making it use Special moves with its abysmally low Sp. Atk. It's not going to hurt anything. Learn what the strengths and weaknesses of your Pokemon's base stats and learnsets are and build movesets and EV spreads to compliment them.
8. Tackle and Growl; WTF? Like I said in 5, there are moves that are obviously stronger than the ones you're using right now with just as much accuracy. Use those.
Any questions?
