One of my currently favorite teams is doubles.
I have an adamant 252 atk (wherever else you feel you need it) Conkeldurr with Iron Fist, Holding Choice Band, and it uses Focus Punch. While it's teammate is Minccino with After You.

Conkeldurr faints just about everything in one hit except for sashers.
150 BP * 1.2 * 1.5 * 1.5 = 405 attacking power not including type effectiveness and Conkeldurr's amazing attack stat.

I also have the same thing with a Mega Camerupt and eruption as backup.

My favorite troll team is my Little Cup team. Set up Rocks or one set of toxic spikes (on this team, poison damage does more than toxic damage) and use Prankster Riolu holding eviolite with Circle Throw/Roar/Rest/ [coverage].

Favorite gym leaders:
R/U/Y: Sabrina. Hime-cut kuudere is the best. Also, she looks cute in a rocket uniform.

G/S: Morty. He has a sweet gym puzzle, and everyone else is only meh. Except Clair. I strongly dislike her.

R/S/E: Tate&Liza. I had a lot of masochistic fun trying to beat the xatu/claydol double battle.

D/P/P: Volkner. Good puzzles.

B/W: Elesa. Model, and it sounds like she has a crush on your character once you defeat her.

B2/W2: Drayden. Truly, the manliest gym ever.

X/Y: Valerie. She is both pretty and unnerving, which is exactly what a fairy type should be. Also, traditional Japanese clothing on all the gym trainers is very nice.

Also vektor, but you other nerds should play with me, there's so many free cards you can obtain it's silly.

Very yes. It's an eerie allure. Haunting beauty. Whatever you want to call it, it's spot on. And the fuurisode girls are all gorgeous, not too mention they give you TONS of xp in the Battle Chateau.

Does anyone have any favorite moves?
Sucker Punch, Acrobatics and Rock Slide are my three favorites. It took me a while to warm up to Sucker Punch, because it can fail. But then i realized if it's failing, then my opponent is failing to kill me.
Acrobatics needed only to be used against me in Gen V, and I was in love.
Rock Slide because I have a triples build where I abuse it.

I'm still trying to find a way to break Storm Throw andor Frost Breath.

OOOH A riddle!
Yes this is a joke, but what pokemon could potntially fit this description? I quickly thought of one, but I'm sure there can be more.

I'm not seeing any, unless you count tails.

I'm not counting tails, but I'm paying homage to the "serious" answer to the riddle.
And, my answer is "arguable", but I feel highly justifiable in that sense.

I don't seem to remember any 3rd stage pokemon with a cane, staff, whatever. At least, nothing that could be construed as a third leg.

It's a stretch for sure, but the reasoning is the same.

That's a wand, not a staff. It's useless for walking.

I mean sure in the actual game, but art and stuff.

Plus we know that wehn Delphox gets a mega-evolution, that's totally going to be a staff. Who are we kidding?

Okay I said I'll do it so let's get this show on the road!

Gen I - Blaine
You know it's kinda of a shame Steel types weren't invented until Gen II because if they had been then Blaine could use them and then he would literally just be old, thin Dr Robotnik. That said Gen I really isn't that hard of a choice; the gym leaders are kinda bland, not through any fault of their own but because this was before they decided gym leaders should be something other then glorified boss fights. So it basically came down to either Koga or Blaine and for me the Hot-Headed Quiz Master takes it by a mile. He's just a fun old crazy mad scientist. Plus his gym made child me think I was really smart for not getting a single question wrong (though Tombstoner should totally be a real pokemon move).

Gen II - Clair
So some leaders you like because they are fun characters or put up a solid challenge or have a memorable gym puzzle. And some you like because it is oh so satisfying to take their dreams, their hopes and their pride and crush them like a cheap paper cup. Twice. Care to guess which camp Clair falls into? I also appreciate that she's one of the few last gym leaders that actually can still put up a decent challenge (that freakin' kingdra...) and I respect her for that. And yes I know she's a child and a bitch but she mellows out a lot once you beat her so it all works out in the end. Point goes to the Blessed User of Dragon Pokémon!

Gen III - Flannery
This was a hard one if only because I barely remember anything about them. Technically Winona has my favourite gym but I can't remember a single thing about her as a character so it's probably in bad form to let her win. In fact I only really remember like three of the characters having personality traits so what ya gonna do? In the end Flannery steals the win if only because I distinctly remember laughing at just how derpy she is - which is nice because with a title like 'One with a fiery passion that burns!' I expected just a retread of the old 'hot-headed redhead' trope. That and she kinda looks like a palm tree and that amuses me.

Gen IV - Gardenia (I guess...)
So I mentioned before I never actually completed Gen IV because it plays so damned slow. I got to about the third gym (though never actually took on Maylene) so it was really only a choice between two people - Roark 'nobody actually calls me the Rock' and Gardenia. Well Gardenia didn't make me climb down into a sodding mine only to run off at the last minute thus wasting all of my time so the Master of Vivid Plant Pokémon get's the vote. Plus I remember the one time in the anime where she full-body tackled a cactus and somehow come off better in that arrangement so I suppose that's worth some points.

Gen V - Iris
...what? You want I should pick Elesa like everyone else? Not until she apologies for that stupid roller-coaster gym. You're a model - what is the connection between models and roller-coasters?! Iris, on the other hand, is just freakin' adorable! Maybe I'm just weird here but I kinda enjoy the fact that in a game where you're booted out of your house before hitting puberty to fight dragons as a profession there is an actual kid who seems to have done alright for herself at it. That and like my Gen VI choice it's nice to see a gym leader who actually travels around and has a bit of an impact on the story. The Girl Who Knows the Hearts of Dragons takes the points.

Gen VI - Korrina
So Clemont probably would have got this if not for the fact I bloody hate his gym with a passion - which is odd considering I liked Blaine's and it's basically the same thing. So with SCIENCE! boy out of the equation my votes goes to the Evolution Fighter (which is a terrible title that makes no sense to the 99.9% of trainers who beat her and then don't receive Mega Evolution). What can I say? She's fun, it's actually nice to see a gym leader who travels more than a mile from there own gym and she not only trains a pair of my favourite fighting types she gives you one free of charge too (admittedly I just took the mega stone off it and booted it into the box but still). That and I like grind rails so her gym scratched that itch.

So I'm guessing one of your favorite champions is Blue then Garren?

Easily. Not sure if he's my favourite since at the point you're beating him at Indigo Plateau you've basically beat him like a billion times and it loops round to feeling kinda bad for the guy. Like I've stared so long into the douche-rival abyss that I've become the douche-rival.

...which is why I like that VI does away with the formalities and just has you playing the rival character. I appreciate that sort of thing.

He was definitely my favorite character to hate.
Every time...

And while I'm here let just finish this off;

Poison is the best type followed by Bug and Grass.
Chesnaught is the best fully evolved starter.
Snivy Smugleaf is the best unevolved starter.
Victini is the best legendary pokemon.
Aerodactyl is the best fossil pokemon.
Johto is the best region.
Cynthia is the best Champion
Professor Rowan is the best pokemon professor
Team Rocket is the best criminal team.
Silver is the best rival.
Bianca is the best friend.

I think that just about covers everything.
