Right, Totodile's attack is much higher then it's special attack, so only use physical moves. Swords Dance will raise his attack, the other moves are just there for mass destruction. You can get swords dance by playing Voltorb flip.
Same story as Totodile, but don't use any special attacks on him, seriously they won't do much damage.
Ah, a special attacker, calm mind kinda fuctions like Swords Dance, raising his special stats.
pfffft... You know, if you needed suggestions for the last Pokemon, I could've helped you. But you should know that I just can't create half of your team.
