While going after my 100 Battle Tower win streak I releaized that there's no way I could win with the Pokemon I had and I've resorted to my one and only option-EV training.
I've heard about it before, but I thought it was just too boring (having to defeat the same Pokemon over and over again)
But then I found out what the Pokerus really does. And I read about the Power Items. With those two on a pokemon I can cut the time it takes to train by 90% (instead of fighting about 250 magikarps, I just kill 25 of'em)

But then I found out about IV Breeding.
It's where you breed two pokemon withonemax IV each
(IVs are like natural talent on one stat)to get a child pokemon with 2 Max IVs.

What really made this easy for me is the fact that someone on the HGSS Trading Boards generouslygave me a free shiny ditto with allmax IVs.

I made this team after all this hard work (all at lv 100):

Smeargle (Lead)
Ability: Own Tempo
Moves: Spore/Stealth Rock/Spikes/U-Turn
Item: Focus Sash

Gengar (Special Sweeper)
Ability: Levitate
Moves: Shadow Ball/Thunderbolt/Focus Blast/Pain Split
Item: Life Orb

Absol (Physical Sweeper)
Ability: Super Luck
Moves: Sucker Punch/Night Slash/Arial Ace/Super Power
Item: Choice Band

Porygon-Z (Special Sweeper)
Ability: Adaptability
Moves: Tri Attack/Thunderbolt/Ice Beam/Dark Pulse
Item: Choice Specs

Gardevoir (Support)
Ability: Trace
Moves: Wish/Wil'oWisp/Psychic/Thunderbolt
Item: Leftovers

Blissey (Special Wall/Staller)
Ability: Natural Cure
Moves: Toxic/Protect/Softboiled/Flamethrower
Item: Leftovers

Smeargle has the job to set up Stealth Rock and Spikes wich give a big advantage.
Spore helps him do that. The sweepers are just there to wipe out the enemy (they have really high attacking stats)

Gardevoir helps the sweepers with Wish, but it has a decent Sp. Attack so it may deal a bit of damage too.

Blissey has a different type of battling in which it poisons the foe with toxic then trys to survive with Softboiled and Protect until the Poisoning eats them up. It also has flamethrower toget a super-effective hit on posion-immune steel types.

I think this is a great team. The only thing I might change is Smeargle's U-Turn to Destiney Bond.
But then he won't have an attacking move so he gone if somebody uses Taunt.
