I use the 5 pokemon from my sig (or their evolved forms) and then change the other 1 depending on preference at the time

Azumarill.
Dang, that thing is a Beast. xD Rain Dance + Waterfall = Beastly.
I also use Furret quite a bit as well.

 

[Harkett]

Heracross, and without a doubt Dragonair.

 

[Zetta Awesome]

Heracross and Zapdos, and I remember generally not using fully evolved rental pokemon because they had horrible movesets.

 

[Conker]

I only could use rental Pokemon, and somehow made it through the first round. =D My most used was easily Kadabra, with Psychic and Thunderpunch ripping through a lot.

Same here, Kadabra rip though the Gym leaders.

 

[Leki]

Well, in about any team I make to fight in the Gym Leader Towers...

Haunter, Dragonair and Parasect.

I loved Haunters speed and Destiny Bond, Dragonairs range of attacks and Thunder Wave, and Parasects Spore and Slash.

Kadabra mainly.

[shaq-attack]

I always used my favorites, so yeah, it was always the really weak rental Pokemon.

Houndour... It had an awesome moveset and got me out of some tough matches.
