I started with Torchic, and he's been doing well for me. Here's my current lineup. Any advice for changes that can easily be made in Sapphire, please, tell me! I'm on the 5th gym now.
Combusken (29 LV, 79 HP, 66 ATT. 39 DEF. Sp Attack 55, SP DEF 40, Speed 44.)
Pelipper (31 LV, 82 HP, 39 ATT, 75 DEF, 61 SP ATT, 49 SP DEF, 55 SPEED)
Mightyena (27 LV, 80 HP, 53 Att, 50 DEF, 42 SP ATT, 41 SP DEF, 50 Speed)
my main ones, extensive training on
Sandshrew (17 LV, 45 HP, 37 ATT, 34 DEF, 16 SP ATT, 18 SP DEF, 20 SPeed)
Swablu (18 LV, 49 HP, 22 Att, 28 Def, 18 SP ATT, 36 SP Def, 28 Speed.)
Looking at this they need a LOT of work. The best moves for each are:
Combusken: Double Kick
Pelipper: Wing Attack or Water Gun, Supersonic works well too.
Mightyena: Bite
Sandshrew: Dig
Swalbu: Sing
