Crawdaunt variant is extremely disruptive and if built right you can remove up to 15+ energies. You don't need the damage output if the guy runs out of energies. You mainly have to do is don't deck yourself out.
I've tested with Swampert and combo with Slurpuff/Empoleon makes it so you will always draw what you want. It also isn't very hard to do this either. It's a good combo but takes up a slot.
My only issues is the stalling and ties. Game 3 should determine a winner by prizes left. I think that would make bo3 better. The stalling piece will be there no what I think.
Pyroar is slow on its own count. There isn't a safe way or a consistent way to bring M Charizard X out. Lots of decks now have early pressure so slow decks get hammered too quickly.
I'm probably going to test play alot on tcgone.net if anyone wants to join me there. I'm a top 16 regionals away from getting my invite and my kids can't stop making fun of me since both of them got there junior invites already. I'm also thinking of stop deck building for them lol.
I play a similar deck and I highly suggest you take out one baby Yveltal for another enhanced hammer. You will need it for your donphan match up and switch out one of your DCEs for 1 dark. You will need it for Keldeo switching.
-1 Yveltal
-1 DCE
+1 Enhanced Hammer
+1 Dark Energy
Congrats on Top 4 MLK and that Yveltal deck that you lost to seems to be the play right now as not many play Zapdos/Manectric from what I'm seeing. I am guessing though we all will see more Donphan when Regionals comes around, its just too easy of a deck to play and do counters with other decks...
