my second sp sweeper for type coverage been pretty good

the reason all my descriptions are so short is because most of these pokemon dont fit well and need to be replaced or changed.
i just need help finding a
PHYSICAL SWEEPER(maybe infernape?)
change gengar's set
and a last pokemon(healer/mixed wall/staller preferably)

Like Delko said, please increase your description. Even though you are going to change your team eventually, you must tell us in great detail as to why or what you want your Pokemon to do for your team. Also please fix your grammar. It looks very sloppy and unprofessional. If you already knew that your team had many flaws, then why would you post it on rate my team? Anyways I'll go ahead and rate your team:

Weavile: Beat up, although unpredictable, doesn't really matter in the long run. Leads are meant to do as much damage as possible to the opponent before kicking the can. Night Slash is the better option for a powerful STAB, and high crit percentage. Ice Shard is risky, but Weavile can out speed most Suicide leads except maybe Aerodactyl, but then again they most likely carry Focus Sash's. Ice Punch is better in the long run. Shadow Claw......meh I prefer Fake Out or Taunt.

Gengar: A special sweeper, but can't pull off one for long due to many will out speed him and OHKO. Gengar is a good Substitute Sweeper.

Weezing: You already have a poison type, and it also knows Sludge Bomb. There are many tanks out there better than Weezing that can also inflict many status problems.

Okay I'm going to just stop and say you need some tuning up to do before I can finish the rate. Your team has many flaws that need to be fixed. Your team seems to be based upon sweeping and tanking. Weavile is good, and Snorlax has potential. You need a better team fit for a wide vareity of rolls. My team consists of:

Lead, Mixed Attacker, Supporting Tank, Rapid Spinner, Special Sweeper, and Bulky Physcial Sweeper.

I have two sweepers, one physical and one special. Some of them have a status inflicter of some sort also. That's all you need for your basic OU team. You don't need more than one unless you have a grand setup such as a baton passer or rain dance with swift swim.

Hope this helps, and I promise to finish the rating when you are satisfied with your team.
