I beat the living crud out of the first five people, but the last guy (i call him Mr Basketball, I can't remember his name) has Pokemon too tough for mine. Here's my team (i'm not changing it, but i know i need to get their levels higher) and this isn't for ratings, just to know if their levels are high enough, or if i need to train them more at The Under colosseum
lvl. 51, Brave nature, Quick Claw
Rain Dance (to help with Thunder)
Aurora Beam
Gust
Surf
lvl. 48, Rash nature
Rain Dance
Thunder
Spark
Quick Attack
lvl. 47, Gentle nature, Exp. Share
Sunny Day
Stomp
Bite
Fire Blast
lvl. 49, Quirky nature, Spell Tag
Psybeam
Perish Song
Pain Split
Shadow Ball
lvl. 51, Bashful nature
Confusion
Return (may replace with Morning Sun, maybe Confusion will go)
Psychic
Psybeam
lvl. 49, Careful nature
Bite
Mean Look
Taunt (useful for things that use Protect or Destiny Bond a lot)
Faint Attack
one last thing: once you beat Mr Basketball (the fat dude) do you get to trade with the GBA games? or do you have to do something like on FireRed and LeafGreen?
