I have lost four battles in a row with this team...

[Pirate Dave]

I posted this on one of the sticky threads and was told I had put it in the wrong place, so here it is in its own thread:

Can anyone give me some advice on my team? Currently it is:

Gallade, Adamant @ Big Root
*Psycho Cut
*X-Scissor
*Drain Punch
*Swords Dance

Gyarados, Jolly @ Splash Plate
*Earthquake
*Waterfall
*Ice Fang
*Dragon Dance

Mismagius, Modest @ Spooky Plate
*Shadow Ball
*Psychic
*Magical Leaf
*Calm Mind

Alakazam, Modest @ Mind Plate [My favorite :)]
*Psychic
*Shock Wave (Might be Focus Blast soon)
*Calm Mind
*Recover (Might be Energy Ball soon)

Tyranitar, Adamant @ Dread Plate
*Earthquake
*Crunch
*Rock Slide
*Toxic

Glaceon, Modest @ Icicle Plate
*Ice Beam
*Shadow Ball
*Water Pulse
*Hail (To make use of its Snow Cloak ability)

... and I have been beaten 4 times in a row...

The people I battled mostly said that I lacked speed, although this is probably because I have only half EV trained them; i.e. each one has only its ATK or SPATK stat EV trained.

They also said that my team was a bit 1-Dimensional, as you maybe able to tell my favorite types are Psychic, Ghost and Dark - if I thought I could get away with it i would just use those 3 types...

Anyway could someone either give me an example of a good team (Probably a good idea to include Alakazam as he is my fav ;)), or just give me some general advice?

I do have other 'half EV trained' pokemon:
Flygon, Salamence, Leafeon, Lucario, Houndoom, Umbreon, Jolteon, Typhlosion, Gengar, Spiritomb, Rotom and Kingdra.

And some that I will probably EV train at some point:
Dragonite, Heracross, Beldum, Infernape, Staraptor and Elekid.

Any advice would be greatly appreciated. Thanks :)
