I have created a deck (In my head though) of how to defeat Night-March decks and since that seemed popular for the San Jose regionals I think that it will be good. It consists of
Pokemon
x1 Lycanrock GX (either one)
x3 Rockroff
x1 Buzzwole GX
x1 Zoroark GX
x3 Zorua
Trainers
x2 Karen
x3 N
x2 Prof. Kukui
x1 Reverse valley
x1 Mallow
x2 Prof. Sycamore
x2 VS seeker
x1 Pokemon Center Lady (a.k.a Nurse Joy)
x1 Pokemon Breeder
x2 Ace Trainer
Energy
x10 Fighting energy
x10 Dark energy
x4 Double energy
The deck works like this when your opponent starts to load up for Night March use Karen and then Vs Seeker to get Karen back. Also hit hard with the GXs
