I'm currently playing through Crystal, about to fight the Elite Four.

>"Matchstick" - Typhlosion
>Level 37 - Male - Charcoal
>Quick Attack/Leer/Smokescreen/Fire Spin

>"Mama Bear" - Ursaring
>Level 37 - Female - Pink Bow
>Faint Attack/Rest/Strength/Fury Swipes

>"Slippy" - Quagsire
>Level 37 - Male - Mystic Water
>Surf/Amnesia/Slam/Earthquake

>"Moon-Eye" - Xatu
>Level 37 - Female - Sharp Beak
>Future Sight/Leer/Night Shade/Fly

>"Daisy" - Sunflora
>Level 37 - Female - Miracle Seed
>Sludge Bomb/Growth/Solar Beam/Sunny Day

>"Boarealis" - Piloswine
>Level 36 - Male - Never Melt Ice
>Earthquake/Powder Snow/Endure/Icy Wind

Any suggestions for move replacements/held item replacements are welcome.

Currently thinking about getting the TMs for Fire Punch and Thunder Punch for Typhlosion and Blizzard for Piloswine (though that's gonna take a lot of grinding at the game corner to get the TM). Someone also suggested Ice Punch for Quagsire, but I don't know about that given Quagsire's low Special Attack and lack of Ice STAB.
