It's been a long 55 hours of gameplay since I started playing Pokémon Diamond, it is officially the game I have played for the longest time on my first playthrough, there are so many things to be done that I just can't stop. Right now I'm breeding Eevees while training my Dratini and Haunter. So, I've decided my team is going to be the following.

Gengar:
Hypnosis
Dream Eater
Destiny Bond
Shadow Ball

Medicham:
Hi Jump Kick
Force Palm
Recover
Psychic

Roserade:
Solar Beam
Petal Dance
Sludge Bomb
Giga Drain

Dragonite:
Thunder Wave
Thunder Bolt
Dragon Rush
Earthquake

Empoleon:
Hydro Pump
Surf
Brine
Blizzard(Ice Beam)

Charizard:
Flamethrower
Heat Wave
Sunny Day
Fly

I'm not sure about Empoleon's Ice attack, I've always loved Blizzard but I heard some people bashing it, because it isn't so accurate. I'm also not sure about my Gengar's moveset, but I guess it is great. So Do you think anything should be changed?
