Black Kyurem Ex is the main attacker, I found that with Crystal Wall it survives a whole lot longer. Mewtwo is mainly for dealing with Kyurem's weaknesses. Keldeo is to act as a mini Mewtwo as well as provide status protection. Blastoise is for accelerating energy as well as getting over pyroar. Electrode is for making sure my hand stays reasonably full. One should never discard electric energy when attacking with Black Kyurem's Black Ballista, just water energy should be discarded.

Why not run Exeggcute (Propagation) which would be extremely useful as easy retrievable discard fodder (needed for your SERs and UBs)?

IMO, the Crystal Wall only provides you very temporary protection - till the time your opponent can Scrapper/Megaphone that Item away... I'd believe you would be better served with either Computer Search or Dowsing Machine as your Ace Spec.

Should you play against most Garbodor decks, I believe you would find that your 1 Startling Megaphone will not be sufficient; in addition, it could be prized in some games. I would suggest you run 2 (or replace your current Ace Spec with Dowsing Machine).

Similarly, 1 Lysandre is insufficient too, IMO.

Given the above comments, following are some suggested changes for your consideration:

-1 Voltorb​

-1 Electrode. Although this provides some supplemental card draw support, you run the risk of not ever getting this setup since it is only a 1-1 line. Secondly, should your ever start with Voltorb, chances are very high it will be KOd (even Electrode is an easy 1HKO target too).​

-1 Crystal Wall​

-1 SER. I found that 3 were quite sufficient.​

+1 Startling Megaphone
+1 Dowsing Machine
+1 Exeggcute (Propagation)
+1 Lysandre​

Lastly, IMO a 3rd BKEX would prove more useful than a 2nd Mewtwo EX or incorporating a Kyurem (PF) (for the 2nd Mewtwo EX) in order to snipe your opponent's benched Poké or serve as a non-EX attacker.

I hope you find these comments helpful.

Thanks for the advice. The main I wasn't running exeggcute, or the other ace-specs was price. I'm trying to keep this deck as inexpensive as I can. Thankfully a lot of the major pieces I'm getting from a friend for relatively cheap. I was tossing around the idea of extra Lysandre and Megaphones, and now I have some ideas as what to remove to work them in. I plan to mostly use ths for league, and yeah I know crystal wall goes easily, but usually in test games it gives me the chance to survive Dragonite EX and then often I heal with pokemon center lady and retreat so that Mewtwo gets the chance to take on dragonite. If I had the extra money I'd definitely get exeggcute and dowsing but thats just extra money i don't have readily available, nor do I have anything currently worth trading that I can trade.
