Here's an Idea For standard since I didn't see any expanded VerGen recently.
4 Bronzor FCO
3 Bronzong PHF
1 Bronzong BREAK
3 Genesect EX FCO
2 Aegislash EX
2 Shaymin EX (ROS)
Trainers: 32
4 Professor Sycamore
2 N
1 Lysandre
1 AZ
4 VS Seeker
4 Ultra Ball
2 Battle Compressor
4 Trainers’ Mail
2 Float Stone
4 VS Seeker
2 Fighting Fury Belt
1 Muscle Band
1 Super Rod
Energy: 11
11 Metal
Idea: Discard Metal Energy with Ultra ball or compressor Metal links causing more potential damage.
Note: I have not seen this do well in competitive Standard play
Nice list! I've tested a very similar deck on TCGO, and it worked well enough and was quite a bit of fun.
Not sure if its exactly competitive or can keep up with some of the more standard decks though.
I would recommend some Heavy Balls too, and a few more float stones. They are quite helpful to let you switch attacker in and out while Bronzongs do their thing. Not sure if Bronzong Break is really needed. Oh, and Fighting Fury Belt wasn't too helpful - with the rate you're attaching and discarding energies, Genesect should be able to one shot most things. And, for those that it can't, it can either tank the hit or it'll be knocked out anyway - I've never really had a situation where FFB would have saved the day. Usually the flexibility from Float Stone would have been better. In fact, the problems I've usually ran into is needed a float stone but not having one.
