What are some good moves for a Pokemon team with Empoleon Lucario Garchomp Dragonite flygon pidgeot?

To start, your team is too weak to Dragon and Ice, I suggest changing Flygon with a Venosaur to have a better type coverage.

A good moveset to make Emploeon the lead of your team would be Stealth Rock/ Surf/ Ice Beam/ Grass Knot, you should also make it hold a Petaya Berry.
