What can I replace Chestnaught and Lamepent with?

I am right outside the Elite Four and feel that Lampent is too weak and Chestnaught isn’t cutting it for me, I am not good with defensive type Pokemon. I might competitive battle after I beat the game, but I am not sure. Just putting that out there for more options.

Here is my current team:

What could I replace them with?

Since you seem to be very offensively minded, I suggest Gogoat as a substitute for Chesnaught. It has the Grass typing which makes a nice F/W/G core (doesn’t matter too much in-game but eh xD), and good mixed attacking stats backed up by a huge movepool.

Suggested moveset:

As for Lampent, I actually think you should keep it, but evolve it. Chandelure is a really strong Pokemon, with base 145 special attack which totally wrecks and it also has decent bulk and speed. Keep the same moves you have, they are good.
