Sapphire Team

[OpallapO]

I'm going to do a playthrough on Sapphire and have been planning my team out. I'm starting with Mudkip, and from there I've chosen Pokemon I like the look of and then narrowed it down to make a (hopefully) okay team for beating the game. I've listed the Pokemon as their final evolutions. I would also like suggestions for a sixth team member, as at first I chose Zangoose, made a moveset for it, and then realised you cannot catch it in the wild on Sapphire
