TBH Dawn Wings isn't really a good card. If it sees play, it will just be for the Invasion Ability. If you want though, you could probably make a fun deck based around Lunala-GX with a tech Dawn Wings for the Ability and GX attack. That would look something like this:
Pokémon (15):
2x Lunala-GX
2x Lunala (Guardians Rising)
2x Cosmoem
4x Cosmog
1x Dawn Wings Necrozma-GX
3x Tapu Lele-GX
1x Alolan Vulpix
Trainers (33):
3x Sycamore
3x Cynthia
3x N
1x Skyla
2x Brigette
3x Guzma
4x Ultra Ball
2x Field Blower
4x Max Potion
2x Float Stone
1x Rescue Stretcher
2x Choice Band
4x Rare Candy
Energy (12):
12x Psychic Energy
