Suggestions for fighting Necrons?

My buddy and I are playing this Sunday. He’s got Necrons, Awakened Dynasty with a C’Tan Shard of the Void Dragon. I’ve typically gotten shot off the board bc I don’t run enough transports but fixed that this time along with some tanks.

I will post the list below that I’m thinking but just general advice for Necrons would also be great; is it best to just out score them and don’t bother trying to wax units off the board?

Thanks for any help you can provide!
