Vir/Gen’s primary strategy is getting a turn 2 Emerald Slash. Running a Call for Family type Pokemon undermines this. Unless Lugia EX or Yveltal EX is huge in your area, you don’t really need this guy for his second attack either.
-1 Sacred Ash
The reason Vir/Gen decks ran Super Rod in the past was for energy recovery. Unless you foresee the frequent need to recycle your Beartic line, Sacred Ash is unnecessary.
-3 Silver Bangle
Beartic OHKOs Landorus EX with a Muscle Band, and OHKOs Pyroar without one. If you were running it for Dedenne, you might want to reconsider why you would devote 5 spots to counter Plasma Lugia, and an already favorable and probably non-existent Yveltal matchup.
-2 Grass, -1 DCE
As an attempt to decrease your energy count a little bit. I’m also going to suggest adding energy switch below, which will alleviate the need of hitting DCE in order to attack with Beartic.
+1 Plasma Energy
I’d ideally like to fit 4 Plasma Energy into the deck, as Red Signal is just such a strong ability. Problem is, there are only so many turns where you will have the luxury of attaching a non-basic energy, and you’re running DCE as well.
+1 Professor’s Letter
I can’t tell you how many times I would have missed a turn 2 Emerald Slash had I not been able to Skyla for Professor’s Letter. I consider this a staple in the deck.
+2 Energy Switch
Mainly used to preserve energy that Virizion EX no longer needs. Allows you to keep G-Booster rolling, also gives you more outs to powering up a Beartic in 1 turn (besides DCE.)
+1 Genesect EX
May be unneeded considering all the alternate attackers you are running, but its the number I prefer.
Will increase your odds of pulling off a T2 Emerald Slash, as well as preserve energy that would be used to retreat.
For the last spots you could add another Skyla, Colress, or Juniper. You could add a 4th Virizion EX (what I’d go with if you decide not to add another Genesect.) You could add Colress Machine, Plasma Ball, or Ultra Ball. Those would be my considerations.
