[RATE MY TEAM] Kanto Classic my first (terrible) attempt

[AttilatheFun87]

This is my first (albeit terrible) team build. I need to find a 6th pokemon but I haven't figured out what yet. I'm considering lapras but I'm not sure yet. The only thing I'm not entirely decided on yet is if I want to make Clefable physically defensive giving it calm mind and making tentacruel specially defensive. Any feedback is appreciated.

You have a major weakness to Nidoking, which is extremely common since everyone is running it to counter Clefable.

Hmm your right I didn't think about Nidoking
