D/P/Pt HeartGold/ SoulSilver UU Team for Shoddy Battle - RMT?

This is my UU competitive team that I use at the moment:


Thanks to Raven Kouryuu for the trainer sprite.

Ambipom @ LifeOrb
Ability: Technician
EVs: 6 HP/252 Atk/252 Spd
Jolly nature (+Spd, -SAtk)
- Return
- Fake Out
- Taunt
- Low Kick

Simply one of the best leads in UU - Low Kick is there as it 2HKOs Registeel and some Steelix.

Mismagius @ Leftovers
Ability: Levitate
EVs: 50 HP/252 Spd/208 SAtk
Timid nature (+Spd, -Atk)
- Shadow Ball
- Nasty Plot
- Substitute
- Hidden Power [Fighting]

My nasty plot sweeper and pseudo-spin blocker.

Blaziken @ Choice Scarf
Ability: Blaze
EVs: 252 Atk/6 Def/252 Spd
Jolly nature (+Spd, -SAtk)
- Blaze Kick
- Flare Blitz
- Thunderpunch
- Superpower

Blaziken revenge kills most Pokemon that try to sweep my team with over 400 speed (after scarf).

Venusaur @ Leftovers
Ability: Overgrow
EVs: 6 HP/252 Atk/252 Spd
Jolly nature (+Spd, -SAtk)
- Sleep Powder
- Swords Dance
- Earthquake
- Power Whip

A great bulky sweeper and bulky water counter (sleep powder's always useful too).

Azumarill @ Choice Band
Ability: Huge Power
EVs: 6 HP/252 Atk/252 Spd
Adamant nature (+Atk, -SAtk)
- Aqua Jet
- Waterfall
- Double-edge
- Ice Punch

Irrestible due to Azumarill's insane attack stat - it can revenge kill with Aqua Jet too, and sometimes even sweep with it late-game!

Registeel @ Leftovers
Ability: Clear Body
EVs: 252 HP/100 Atk/156 SDef
Careful nature (+SDef, -SAtk)
- Iron Head
- Earthquake
- Thunder Wave
- Stealth Rock

Registeel is a lot more defensive than the rest, but he seems to hold my team together nicely.

so, what do you think? I may write more explanation on eventually...
