Cool team, you've got a major Bisharp and Ground weakness though. Bisharp just 6-0's this team, surely? And there's no good switch-in for offensive Grounds, so things like LO Excadrill or offensive Lando-T will at the very least force Slowbro to M-Evolve early and be under a lot of pressure to keep healthy. Hazard stacking from the likes of Ferrothorn (or even just Rocks from Grounds / Tran) could be irritating, but at least the team has the potential to outplay. Finally, the rare CB Tar lacks a good switch-in.
The main issue is that there's a lot of redundancy between Azu / Clefable / Chansey, so one of them can easily be replaced for something along the lines of Chesnaught. I'd recommend Azumarill, but whichever really.
