Wynaut, here's my team for singles in World Tournament:
Sableye
~Leftovers
~252 HP, 252 Defense
~Modest
~Prankster
-Calm Mind
-Will o wisp
-Recover
-Dark Pulse
This Sableye can stall out and set up on a lot of Pokemon. It can tank from both sides thanks to Calm Mind and Will o wisp, and also has an immunity to a good amount of attacks. After a few Calm Minds, Dark Pulse hits fairly hard. The main weakness of this Sableye is Pokemon with Guts, Pokemon with Toxic and sleep moves, Fire types, and special attackers that hit very hard. Will o wisp's unreliable accuracy is also an issue.
Modest definitely works perfectly fine over defensive natures due to priority on WoW/CM, but on the topic of inaccurate WoW, perhaps Bold would be worth consideration. If PWT opponents switch as often as Subway foes do, then this set looks like it's pretty dominating against anythin' not using Band/Specs. And crits as well, 'course.
Ditto
~Focus Sash
~252 HP
~Imposter
-Transform
Because entry hazards are very uncommon here, it's safe to run a focus sash. I chose it over scarf since there's some Pokemon it can copy that suck if they're locked into one move. I mostly have it to counter set up Pokemon, and it's fun to use as well.
bleh
Sharpedo
~Life Orb
~252 Attack, 252 Speed
~Adamant
~Speed Boost
-Waterfall
-Crunch
-Earthquake
-Protect
A last resort cleaner that can go in if Sableye is taken out. It outspeeds pretty much everything thanks to Speed Boost, and hits pretty hard hard with that attack stat.
Just ain't strong enough IMO, but I ain't gonna stop ya from usin' your trademark fish by sayin' "there's so much that does this job better", am I?
In rotations and doubles, I add this Hydreigon.
Hydreigon
~Dragon Fang (I'll probably replace it soon)
~Modest
~252 Sp. Attack, 252 Speed
~Levitate
-Dragon Pulse
-Earth Power
-Flamethrower
-Surf
Hydreigon is capable of OHKOing most Pokemon with its attacks, which would be even more dangerous if I got a better item for it. It outruns most opposing Pokemon, which is good. I might replace Surf since it can't be used in doubles well with this team.
needz moar timid. Though if ya would do so, a damage-increasing item would be rather necessary. Unfortunately, the dark-shark takes the LO, and I know you ain't much for choice items. Along with the fact Fightin' types have their way with half the team, all of my favorite Dragon's bias aside, I recommend ya swap it out for Latios IF, and only if, this team ain't doin' ya justice. Soul Dew boosts SpD and obviously SpA without keepin' ya locked in moves. Latios is faster, stronger, bulkier on the special side, and STAB Psychic is better than STAB Dark Pulse for the team. Regardless of whether the pseudo or the true legendary dragon is better, Latios is clearly better for this particular team.
That aside, if you're gonna keep Hydreigon like I damn-well know ya will, keep Surf. Protect on 'Pedo and Hitmontop let ya use if whenever need be really, and Ditto has the situational chance of mighty morphin' into a Poke that can comfortably take a Surf; hell, maybe even a Poke with Water Absorb. Drop either Earth Power or Flamethrower depending on your preference/whichever offers better coverage for Protect. When that Mach Punch Conkeldurr or speedy Mienshao is starin' ya down, you won't regret said choice.
Also, in doubles, I replace Sableye with this Hitmontop:
Hitmontop
~Leftovers
~252 Attack, 252 HP
~Adamant
~Intimidate
-Fake Out
-Mach Punch
-Hi Jump Kick
-Protect
A useful Hitmontop to use in doubles. It hits hard, can flinch the first turn, and has priority in Mach Punch, and can lower opposing attack power with Intimidate. It has a huge problem with Ghost types, though, so I may replace one of the moves with a coverage attack.
We've got a clash of movesets here... Without Technician, both priority moves are rather meh. With lefties takin' the place of Life Orb, they're really meh. If ya want to keep the moveset as is, just replace Mach Pawnch with Sucker Pawnch. Ghost problem solved with a middle finger to not-Reuniclus Psychic types as a bonus.
If ya don't like that option (yes, what I'm suggestin' is 9001% better than what you've currently got IMO), make it offensive instead of supportive. Keep the moveset as is, give it Technician and a Fighting Gem. Mach Punch with the gem and Technician is just-plain scary after a Fake Out. If Mach Pawnch's priority is ever unnecessary, STAB Gem-boosted HJK is just insane regardless of a Poke's base Attack. Whereas Intimidate lets ya soak hits better to dish out more, boosted Fake Out & double-boosted Mach Punch lets your team mate dish out more pain by killin' off a threat immediately; a threat that might not care for Intimidate if it's a Special attacker.
Regardless of which one ya pick, I highly recommend switchin' to one'a my alternative moveset ideas if either of 'em catch your eye.
No team for triples yet.
THEY HAVE TRIPLES/ROTATION TOURNAMENTS?! yey
