Can see the idea but not sure how it will work. Being that your energy accelerator is a Stage 2, which can be
very slow compared to a lot of decks in the format now but this how I would maybe play it...
Pokemon 15
3 / 2 / 3 Emboar (Ability)
4 Mewtwo ex......Legend lol
RDL is actually great when played at the right time. 3 prizes off of one Mewtwo KO? Yes please!
1 Cleffa ......maybe not ideal start....but running a Stage 2 could come in handy with set up.
1 Shaymin UL.....damaged Mewtwo.....switch all energy onto the next one before a knock out.
I think SSU might be a better play in this case. You'll still have that damaged Mewtwo on your bench for an easy 2 prizes.
1 Shaymin ex.....great tech and can hit a lot of damage if you go behind.
I don't really see it. If anything add a Reshiram or two.
Energy 14
8 Fire
4 DCE
2 Rainbow..... For Shaymin ex, could possibly change for a grass, but maybe not going to be used every game but just in case with Mewtwo ex.
If you're bent on keeping Shaymin EX, Prism is much more ideal.
Trainers 31
4 PONT
Maybe drop to 2 and add in 2 N. This deck can be slow at times and N is a good disruption for when your opponent takes early prizes.
4 Junk Arm
4 Rare Candy........up the Candy get Emboar ASAP
3 Duall Ball......a lot quicker than Collector on its own since you only need Emboar and Mewtwo ex out
most of the time.
3 Juniper
3 Pokemon Communication
2 Pokemon Catcher
2 Cilian......grab Fire energys.....onto Mewtwo!
2 Collector
You really don't need both DB and Collector. Drop one for Switch. Anything involving Emboar needs Switch.
2 Super Rod......more choice over Energy Retrieval
ER is better because the energies go straight into your hand for you to attach.
2 Twins
