I think your Trainer line is a little eclectic, as I'm not sure what you're going for with it. It seems you're trying to do the defensive / disruption build. Two Crushing hammers isn't going to cut it for this. That card is only good when you play four of them, since you need to maximize your chances of removing energy. I'm also not a fan of Malamar-EX myself. The Ability will only matter 50% of the time (if your opponent gets tails between turns) and will do you no good against VirGen. Even then, Sleep can be nullified by a Switch, Keldeo, etc. The attack is also not very reliable. I'm not a fan of flip cards because they have a tendency to fail at the worst moments. Pokemon Center Lady is really inferior to other healing cards, and you only need one Switch since you can free retreat with Darkrai-EX. Keldeo-EX can also be used in combination with Dark Cloak for Rush In / Retreat, and is more reliable than Switch. Since it seems you're going the defensive Yveltal route, I'm going to suggest changes to improve that. Alternatively, you could go with the "Classic" / "Speed" build, and run Laserbank.
-1 Malamar - EX
-1 Pokemon Center Lady
-1 Switch
-1 Ultra Ball
-1 Shadow Circle
+2 Keldeo-EX
+2 Crushing Hammer
+1 Muscle Band
You can also opt to remove the Energy Switch in favor of draw / consistency, maybe an Escape Rope, depending on your playstyle. I think Energy Switch is best played in counts of 3 or more, and only if you plan on attacking with Darkrai-EX. All in all, the list looks pretty solid aside from Malamar. The changes I'm suggesting are mostly minor tweaks to maximize your odds of success, other than adding the Keldeo which I think will be helpful all around. Best of luck to you!
