Blastoise @ Modest
idk @ Torrent
~Surf
~Ice Beam
~Toxic/Earthquake
~Skull Bash/Body Slam (IMO)
Surf for STAB, Ice Beam for Grass, Toxic for when you plan to switch, or Earthquake for Electrics, and I like Skull Bash a little more because the raise of Def makes up for the waiting a turn, or you could use Body Slam (need a tutor IIRC)
Pidgeot @ Adamant/Jolly
idk @ Keen Eye
~Aerial Ace/Wing Attack
~Steel Wing
~Featherdance/Agility
~Fly (filler)/Double Edge (give Leftovers)
Raichu @ Timid/Rash
idk @ Static
~Thunderbolt
~Brick Break/Iron Tail
~Body Slam
~Thunderwave
I rarely use Raichu, or electric types for that matter because of small movesets, but this is what I would use. As for Brick Break/Iron Tail, Iron Tail's accuracy is shaky, but only use it if you give Beedrill Brick Break
Butterfree @ Bashful
idk @ Compoundeyes
~Silver Wind
~Aerial Ace
~Psychic
~(filler)
I have used this Butterfree with relative ease in the past, so it is a good moveset IMO. For the (filler), maybe try Whirlwind for POKéMON it's not going to beat *cough* *couch* Bruno *cough* *cough*
Beedrill @ Adamant/Jolly
idk @ Swarm
~Aerial Ace
~Brick Break
~Sludge Bomb
~Agility/Swords Dance/Pursuit/Twin needle
Aerial Ace+Brick Break=great coverage. Sludge Bomb gets STAB, plus a chance of badly poisoning the foe, and for the last slot, I don't know.
Lapras isn't needed when you have Blastoise, and for that matter, maybe drop Beedrill also.
