White 2 PWT team

[ECM]

I want a team that can hold its own in the Pokémon World Tournament, but I'm having trouble deciding whether I'm choosing good movesets, or if I should even change some Pokémon on my team. I haven't cared too much about natures in the past, but if you have a suggestion for a change in nature on one of my Pokémon, please do not hesitate to tell me. This is my planned team at the moment:

Emboar @Charcoal
Quiet, Blaze
Scald
Solarbeam
Sunny Day
Heat Crash

Lucario @???
Naive, Inner Focus
Dark Pulse
Aura Sphere
Double Team
Ice Punch

Sandslash @Soft Sand
Quirky, Sand Veil
X-Scissor
Swords Dance
Poison Jab/Sandstorm
Earthquake

Ampharos @???
Bold, Static
Rain Dance
Thunder
Signal Beam
Confuse Ray

Weezing @Quick Claw
Careful, Levitate
Toxic
Venoshock
Thunderbolt
Flamethrower/Shadow Ball

Jellicent @Mystic Water
