Legendary Pokémon

I prefer physical Salamence, ´cause it´s Atk is really great. Well, actually, I prefer not using Salamence, ´cause I hate them xP
Crobat looks good... Maybe you could use Nasty Plot and Air Slash too...

For Crobat, use U-Turn and Aerial Ace as the two last moves. Trap whatever comes in to stop you, put it to Sleep then U-Turn to a counter. Aerial Ace is just there for STAB and it's better than Cross Poison due to type coverage. Also, I suggest you go 252 Speed/252 HP/4 Atk, you won't be attacking much, Crobat's aim is to put a Pokémon to sleep. Oh, and U-turning to Dugtrio is awesome for trapping a sleeping Pokémon and killing it w/o risking getting a hit.

About Salamence, I don't know. It depends on whether you need a physical or a special sweeper. It's good enough on both sides. However, if you use a special one, you'll be locked to one move by Choice Specs while in a physical one, you'll have a Dragon Dance for setting up which won't limit you to a certain move.

By, the way, does U-Turn cancel Mean Look´s effect like normal switches? I know that Baton Pass doesn´t cancel it.

Yes, it does cancel the effect of Mean Look like normal switches but it is still useful on Crobat. The turn they switch out their sleeping Pokémon, you can set up the Pokémon you brought out.

Hello! I´d like to ask you for some help. I´ll participate in a tourney. One of the rules say that half of my team should be of the same type. Since I love grass pokemon, I chose the grass type.
What about this team, then? I´m still planning and I´d really like some suggestions.

Bronzong
Relaxed@Shell Bell
Levitate
252 HP, 100 Atk, 158 Def
- Stealth Rock
- Gyro Ball
- Earthquake
- Payback

Unfortunately, my Bronzong has IV 25 of speed, so Gyro Ball won´t be as powerful as it should be xP Well, you know Bronzong´s walling ability. I love to use Stealth Rock, so I decided to use it. Payback may look retarded (specially when there´s Explosion, Hypnosis and somethings else), but it gives Bronzong more type coverage.
I almost forgot... I can´t use Leftovers, because I´m planning to use it on another pokemon, and the rules also say that I can´t repeat the same item.

Torterra
Adamant@Focus Sash
Overgrow
?? HP, 252 Atk, ?? Spd
- Earthquake
- Seed Bomb
- Rock Slide
- Rock Polish
Focus Sash will grant Torterra time to use Rock Polish once. I´ll calculate how many EVs it takes for Torterra to be with 198 of speed - enough for beating everything not-stated up that is used. I prefered Seed Bomb over Wood Hammer because I don´t want to kill my own Torterra.

Ludicolo
Modest@Wet Rock?
Swift Swim
?? HP, 252 SAtk, ?? Spd
- Rain Dance
- Surf
- Ice Beam
- Energy Ball
Same thing as Torterra... I´ll make it have 198 speed to overrun everything fearful while it´s raining. It´s just a special sweeper.

Gengar
Timid@Wide Lens
Levitate
6 HP, 252 SAtk, 252 Spd
- Thunder
- Shadow Ball
- Focus Blast
- Destiny Bond
Wide Lens´ll increase both Thunder and Focus Blast´s horrible accuracu to a slightly better 77. If Ludicolo activates Rain Dance before Gengar is sent out, Thunder won´t ever miss, and may even paralyze. I prefer Focus Blast over Energy Ball just for type coverage...

Blissey
Bold@Leftovers
Natural Cure
252 HP, 252 Def, 6 SDef
- Seismic Toss
- Counter
- Aromatherapy
- Softboiled
Well, a standard countering-blissey. Countering Blisseys aren´t common nowadays, so it may be really surprising for my foes. Since the tourney has recovery-clause (we´re forbitten of using recovery-only moves, like Softboiled, but we can use moves that also damage the opponent, like Drain Punch and Leech Seed), I´m thinking about replacing Softboiled with Shadow Ball, to take away ghosts. What do you think?

Jumpluff
Jolly@Brightpowder
Leaf Guard
252 HP, 6 Def, 252 Spd
- Encore
- Sleep Powder
- Aerial Ace
- Leech Seed
My well-known Jumpluff Of course I´m using it! xD I prefer Chlorophyll, but the only good Hoppip I could breed had Leaf Guard.

What do you think about the team? I tried to balance well its weaknesses...

Your team is really nice.The only thing I would suggest is you might consider replacing one of ludicolo's moves with Leech Seed,so it can get really annoying

Yeah, I thought about that too. But my team almost has no grass moves, although it´s a grass-based team

Consider putting Macho Brace on Bronzong in order to lower its speed. Also, you have some sweepers out there, so it would be safe to replace Payback with a more defensive-styled move.
You hould have thought about that, but you can replace Blisseys Softboiled with Thunder Wave or Ice Beam (but they are more Standar and an opponent might expect them)

But if I use Macho Brace instead of Leftovers, Bronzong won´t have any ways to heal itself. Is it a good idea, yet?
I think I´ll switch Blissey´s Softboiled, then, since I can´t heal her anyways

Thanks! o/

Just, an idea: You could use Hypnosis and Dream Eater on Bronzong to gain some HP, but I don't know how effective could that be. STABed Dream Eater though can give you more HP than SHell Bell and Leftovers can.

If I use Hypnosis, the foe switches out. There´s sleep clause on the tourney, so Dream Eater wouldn´t be used so easily. But Hypnosis is usefuk anyways... I guess I´ll replace Payback with it.

Well, sleep clause is a pain. Replacing Payback was just an idea. Payback is a good move and will catch a lot of your opponents off guard. (and you know that I believe in surprise sets!)

I was planning to train a bronzong but it turned out that we may have the same pkm ( that was off topic ). Anyway i think that you should switch your gengar's focus blast. As you said this team is for battle tower right ? Then if focus blast misses as we all now it is going to miss many more times in a row such as other moves that have better accuracy than focus blast ( and i mean with this that like moves with 100 accuracy miss three times in a row focus blast will miss all time except if you are lucky ) . So i insist on psychic or sthing that you think better than this
