Rate and Improve my pokemon black Team?

Seismitoad needs to replace mud shot with earthquake. There is an Earthquake TM. Lampent already should have evolved, replace inferno with fire Blast, he can also learn Solarbeam. For slot six, use your Sandile, but first evolve it to Krookodile, teach it Earthquake, Crunch, Foul Play, and Flamethrower? Very good overall
