Looking over this set, I see...
The artwork theme this time appears to be more of the BW2 locations (I notice Lentimas Town and the Strange House), plus the rooms that the E4 battle in.
Masquerain: Reminds me of Mismagius GL LV.X. Unfortunately, Masquerain itself isn't very strong. If it were, the ability would have a lot of utility. Salvage those Eviolites for when you really need them.
Lileep: Prevents deckout. Fun. So do the others.
Cradily: It's GCC, not GC, for its second attack. But who cares? Life Explosion is the greatest thing ever!!
Accelgor: I think its first attack is supposed to be Fated Revenge or something, not Revenge and Prataya. I have no idea if 'Prataya' is even a real thing.
Virizion EX: It actually looks pretty nice. Immunity to Special Conditions for Grass Energy holders, and can (relatively cheaply) attach 2 Grass Energy directly from the deck, helping guys like Genesect EX (obviously) or even Cradily. Or that one Tangrowth with Hundred Whips or whatever it's called.
Volcarona: I really like that first attack. Deck thinning like a boss.
Drifblim: Anti-Team Plasma! Attack for free YEEEEEEEEEEEAH (By the way, Derail discards a Special Energy on the target, not any Energy. Says as much on the card.)
Pixie Trio: I'm loving Psy Power and Psy Jamming. Early-game pressure and then later moving around Special Energies like a troll.
Sigilyph: 4 Pokemon Tools? LOLOLOLOLOLOLOLOLOLOLOLOLOLOL /shred
Golurk: That looks so cool. Not battle-wise, but appearance-wise.
Machamp: I'm somehow worried about that. Landorus EX might take over the format again.
Sawk: lolplasmadonk
Archeops: Defeatist! I see it!
Jirachi EX: You're...You're joking, right? You have to be joking; this can't be a real card.
Dialga EX: I don't know about you guys but I honestly think this is a cool card. First attack is pretty nice and no mistake, but I'm more so looking at the second - CCCC for 90, and as an added bonus, mill your opponent for your Plasma Energy's worth. It's like rubbing salt in a wound. I honestly could see this card becoming pretty strong.
Palkia EX: In comparison to Dialga EX, this guy is so utterly underwhelming. I'm saddened. It's got your typical hit-and-run that you see on Palkia often, but the second attack is ew.
Haxorus: Both of those attacks are absolutely amazing. Haxorus in Klinklang gogogogogogo
Druddigon: Oh look, a cheaper Shred. I could see that being used in some other decks as a tech, maybe.
Chatot: -1 Tool Scrapper, +1 Chatot. gg Sigilyph
Root Fossil: Why is there no Claw Fossil? I miss Armaldo!
Silver Bangle: Now we're talking. With this, pretty much any run-of-the-mill Pokemon can mount an attack against Pokemon-EX, dealing 30 more damage to them. I can easily see this in decks that aren't really "exxentric", one possibility being Fluffychomp if we have a DRX-on rotation, but there'll be others as well. Regardless, Silver Bangle is a fantastic card.
Silver Mirror: Another relic of Opelucid, it looks like, granting immunity to Team Plasma Pokemon. Now go stick it on a Sigilyph DRX and you have a funny wall. ...I'm just kidding; that thing dies to Shred.
Reversal Trigger: So, upon Knock Out of a Team Plasma Pokemon, you get to add any 1 card from your deck to your hand? So much for Computer Search. It's like Final Wish, but has anyone actually used Manaphy yet? No. They should.
Caitlin: This is actually a really nice draw supporter, I feel. It's a bit limited in scope, but at least it puts things you don't want where you won't draw them.
Scoop Up Cyclone: It's the classiest way to surrender a game. Have 1 'mon left, play Skyla, search for it, enter scoop phase, gg!
And I believe that's all I have to say about this set. Oh, except for:
SHINY EXEGGCUTE AWWWWWWWWW YEEEEEEEEEEEEEEEAH
