I would try either a Chimchar (Costs 1 Fire) or a Larvesta (Cost 2 colorless). Both do 20 damage, but with a Silver Bangle... that's 100 to either Virizion or GenesectEX... it can be a nice surprise, along with the fact neither is an EX.
Here's a basic Japanese list for the deck:
4 VirizionEX
3 GenesectEX
7...
12 Grass
12...
4 Bicycle
4 Skyla
4 Float Stone
4 Ultra Ball
4 Hypnotoxic Laser
4 Pokemon Catcher
4 Professor Juniper
4 N
3 Energy Switch*
2 Virbank City Gym
2 Super Rod
1 G-Booster
1 Shadow Triad
41...
