Never been to this part of Serebii before... Anywho, I decided to play Platinum again, and being myself I had to plan EVERYTHING out before starting, but I'm not focusing on items or natures. Just beat Fantina a.k.a. one of the easiest leaders ever. Here's the team(when it is finished):

Floatzel
Aqua Jet
Crunch
Surf
Waterfall

I don't really have HM Slaves... but I might put Ice Fan over Surf and just get a bidoof. Floatzel is the Revenge Killer.

Torterra
Earthquake
Wood Hammer
Cut/Synthesis/Leech Seed
Rock Smash

Again with Bidoof. Rock Smash hits what Earthquake doesn't, and Cut is just neutral coverage. Kind of physical wall.

Luxray
Thunder Fang
Charge/Thunder
Crunch
Iron Tail/Fire Fang/Ice Fang

Charge is always useful, and Iron Tail is for coverage(very little but) as is Fore Fang and Ice Fang. Physical Attacker

Noctowl
Extrasensory/Psychic
Air Slash
Fly
Hypnosis/Reflect/Roost

Special Wall. And Staraptor is too mainstream.

Houndoom
Flamethrower
Dark Pulse
Crunch
Thunder Fang

Mixed Sweeper

Azelf
Psychic/Extransensory
Signal Beam
Flamethrower
Energy Ball/ThunderBolt/Shadow Ball

Special Sweeper. I know Azelf is "legendary" but it is my favorite psychic type and I only consider it a "half legendary".

So, what do you think?
