Here's the team I recently beat the Elite Four with! Currently in my sig as well :P
EV trained Eris because she's gonna be on my Battle Subway team I think...
and because it just makes everything easier, I've always wanted to train a Weavile. Too bad she's not shiny ):
Eris the Weavile, female, L62, Adamant, Ability: Pressure
4hp/252atk/252spd
Aerial Ace / X-Scissor / Night Slash / Slash (don't have enough Red Shards for Ice Punch yet, grrr)
I was able to use Eris to OHKO/2HKO most of the Elite 4's Pokemon thanks to her ridiculous stats, but she was a bit useless on the
champ. Still, totally worth the 2 hours it took to train her, I think I'll keep her around.
Genevieve the Jolteon, female, Bold, Ability: Volt Absorb
Volt Switch / Thunder / Shadow Ball / Bite
I need to teach her Dark Pulse if possible... not sure if possible. Sure helped knock out those flying/water types though! I wish I
would've taught someone Rain Dance though, stupid Thunder kept missing at awful times... I love how speedy electric types are though.
Beryl the Starmie, L56, Quirky, Ability: Natural Cure
Psychic / Ice Beam / Surf / Thunderbolt
She ended up getting wrecked a lot of the time on the E4 because of their annoying typage, but still a good asset for the champ and
many of the gyms! Starmie is one of my favorites so it was nice getting to use her. Unfortunately her stats are totally borked and
terrible, although her Sp Atk is good!
Windy the Arcanine, male, L55, Lonely, Ability: Flash Fire
Flamethrower / Aerial Ace / ExtremeSpeed / Fire Fang
I picked Flash Fire because I hate waiting for Intimidate at the beginning of every stupid battle. Arcanine is another one of my favorite
Pokemon, the only thing he really helped me with on the E4 was chipping away at that last bit of HP thanks to ExtremeSpeed though. I
think I'll replace him with a Drought Ninetales for my "useless endgame team".
Topaz the Flygon, male, L52, Naughty, Ability: Levitate
Rock Slide/Bulldoze/Fly/Dragonbreath
His moveset was gonna be better but all of the TMs I wanted to use on him (Dragon Claw, Earthquake) weren't available until after
beating the E4 so I kinda gave up on him. He's a bit of a weakling and I really only used him for some type coverage (and because I love
my Flygon TCGs)
Lox the Lucario, male, L50, Serious, Ability: Inner Focus
Strength / Heal Pulse / Force Palm / Counter
Awful moveset, however he was one of the first Pokemon that I caught so he's kind of just a placeholder in my team for whenever I go
up against some annoying normal type. Kind of helped with the dark-type E4 though.
