[RATE MY TEAM] Need suggestions for improvement

[Revenant L]

I wouldn't really suggest having substitute on Meta-Metagross. Ice punch, Thunder punch, or Grass knot might serve you better. Chandelure could use some improvement too: I would suggest using Overheat over Fire blast, and replacing HP Dragon with either HP Ice or Heat wave. Careful with using a Milotic Mega Metagross lead. Metagross is fairly slow before mega-evolving, so take that into account. I've tried using a Mega Metagross and Mat block Greninja before, and it's fairly useful, so you can try that if you want.
