This team is intended for OU. I tried to make my team defensive, yet a little UU. I kept my sweepers OU while 3 of my walls UU. I'm not sure how good this is so that is why I want smogons guess on how it is.
Uxie - Leftovers
Sassy 252 hp 252 sp.df 6 df (Could I get some help on those EV's?)
-Stealth Rock
-Yawn
-T-wave
-U-turn
I stealth rock. Then I yawn. Then I t-wave. They either get their gyrados t-waved and ruined, or their next switch-in gets ruined.
Quagsire - Chesto
Sassy 252 hp/sp.df 6 hp (this EV set i'm keeping)
-Rest
-Curse
-Ice Punch
-EQ
Practically a wannabe swampert. It can take several hits despite what it seems. I'm choosing quagsire over Swampert thanks to water absorb. I'm not sure about chesto rest though.
Bellossom - Lefties
Calm 252 hp/sp.df 6 sp.atk (this set is repeating itself...)
-Stun Spore
-Sleep Powder
-Moonlight
-Energy Ball
Double powder, heal move, attack move, pretty standard.
Wigglytuff - Lefties
Impish 32 hp, 252 sp.def, 226 defense
-Counter
-Charm
-Seismic Toss

I'm not sure if I should replace Charm with protect. Should I?
Yanmega - Wise Glasses
Modest 252 Sp.atk/speed 6 hp

As you can see other than tuff, my sets are really in need of help. Should I replace Charm with protect?
