This is kind of assuming but it looks like Luxray is your toughest guy here next to Tauros. Also not a lot of type coverage. I tried a team with no fighting type in it a couple playthroughs ago, I made it to Charlotte before my comp crashed but it wasn't a pleasant drive. Hariyama isn't the best type since his awful defense makes him a rather poor tank if fighting something that fighting isn't strong against. You could get Sraggy whose defense and typing are pretty nice, his movepool is decent and that could replace Liepard. If you want to keep Tauros (I don't know enough about his uses to say yay or nay) then change his ability to Intimidate or Sheer Force. Get rid of Simipour (imho any pokemon with less than 500 bst is useless in Reborn) You can replace it with Swampert who has a decent movepool and only one weakness in the not so common Grass type. (Mudkip is found in Byxbision, Rainy day to talk to nerd on stairs, Sunny day to find him in Tauros ride section. Must have all pokemon faint while riding Tauros or have Teleport both require use of Byxbision heal center) Or you can use Piplup which can be gotten from 7th street who becomes Empoleon who has a less than great movepool but only weak to fighting and ground. There's my two cents feel free to use or toss in the swear jar and good luck.
