Tyranitar-You mentioned that your Tyranitar is a she, use a male Tyranitar instead of a female, because male's have a higher attack stat. Use Flamethrower/Fire Blast for the last move. Attach Leftovers.
Charizard-Not bad, but I would replace Body Slam with Swords Dance. Attach Leftovers.
Ampharos-Good, if possible, replace Fire Punch with HP Ice or HP Water. Otherwise, keep Fire Punch, but change Flamethrower/Fire Blast on Tyranitar to another elemental move, perhaps Ice Beam, because you don't need 3 Fire moves in the same team. Also, attach Leftovers!!
Girafarig-Let's see... Replace Crunch with something... Baton Pass wouldn't be a horrible idea, but you don't like it, at least not on Girafarig... I guess if you don't want to go with BP, then use Earthquake or Return. Also, Either Agility or Amnesia will work as a support move. Attach Leftovers.
Kingdra-Kingdra makes a good Sleep Talker. Keep Surf, and then use either Ice Beam or Dragonbreath, (I prefer Ice Beam) along with Sleep Talk and Rest. Attach Leftovers.
Tauros-Standard FishTauros moveset. It works. You could also go with Double-Edge and Earthquake along with Sleep Talk/Rest if you prefer something a little more accurate, but, go with whichever set you like better. Attach Leftovers.
Overall: Not a bad team, no 3x weaknesses. A few of the movesets could use a little reworking, but they look pretty good. It's kinda nice to see some of the underused Pokémon that you have in your team. Leftovers would be the best attachment for everybody IMO.
