Running over the set list for interesting cards...
Cradily - Like Otaku pointed out, tight Stage 2 list that will have to squeeze Basics in just to be legal. If nothing else, Cradily decks will probably be rather mulligan prone, which is not a good thing. Besides, most Stage 2s still aren't on the level of EXes, so you will still see an EX-oriented metagame. However, it has been (over)hyped to the extent that at least for 2-3 tournaments after its release, it will see play.
Virizion EX - This is one of the big ones. Finally the Grass type gets an acceptable form of Energy acceleration! Still, the fact that you can't attack T1(unless you run Team Plasma Badge and get it on T1 along with the Colress Machine and Grass Energy) is a minor downside, considering Genesect EX grabs KOes like nobody's business. Laser immunity for Grass-types is great as well.
Genesect EX - The other really big one(its the mascot...). With T2 Emerald Slash and a Plasma Energy in hand, you can start swinging with Megalo Cannon T3, which is doing a LOT of damage pretty fast, and Red Signal lets you take advantage of the snipe damage easily.
Eelektross - I'm not sure about this, but I think it might make for a nice 1-of in Eels decks(assuming no rotation of course) as a finisher, since you will have Energy scattered around on the field. Obviously you evolve after pulling off all your Dynamotors to get one dose of Crush and Burn. Again, this is really specific, and I would never ever use more than 1 in a deck.
Drifblim - I don't think this can be called anything more than "cute". Sure, against dedicated Plasma decks it will be a free 70 damage Energy Removal, but dedicated Plasma decks will probably easily KO the Drifloon in the first place.
Sigilyph - This card shouldn't be in this format
. In other formats, there would be sooo many wacky thigns you could do, but I can only foresee Rocky Helmet/Rock Guard and Eviolite shenanigans even standing a chance. Then again, almost every deck runs a Tool Scrapper, so they'd probably Scrapper off 2 of the tools before KOing it...
Jirachi EX - It looks like a nice 1-of in combination with 1-2 Super Scoop Ups to help ease Supporter droughts. 90 HP on an EX is crap though.
Haxorus - Very much a poor man's Machamp SF. First of all, it needs 2 Energy(though Blend WLFM can provide it), secondly, its in a format with even better Basics(EXes) than Machamp, and thirdly, Rare Candy is significantly weaker now and Broken Time-Space doesn't exist. Plasma decks would overrun it pretty quickly.
Porygon-Z - Just like Cradily, I think this is receiving more hype than due. Sure, it has applications(such as quick preparation of Plasma's big 2: Lugia EX and Snorlax, and also for Tornadus EX), but its far too slow, and is much too restricted(you may not even have all 4 Plasma Energy on the field at the same time).
Chatot - Really gimmicky card I can only forecast one use for; sacrificial anti-Garbodor(costing only Energy after all). Not a good card at all, but maybe someone will slot it in to deal with Tool-abusers like Garbodor and Sigilyph?
I'm much more speculative on the Trainers.
Silver Bangle - Most big attackers are EXes in the first place. Kyurem could use it, as could Snorlax, but I don't see that large a pool of potential users. It will definitely see play though.
Silver Mirror - Now this can actually be a big deal for Plasma decks. Currently, every attacker used in Plasma decks is Plasma itself(to take advantage of Deoxys EX), and dropping Silver Bangles onto your field can virtually shut them down instantly(particularly if they've run through their Lasers and Catchers already).
Iris - I'm not sure how you'd use this on any non-final turn, since our Supporter engine is
so good already(/sarcasm) that we practically need to play one every turn to keep up. Even on the final turn, its oriented towards decks that play a bit more slowly(and hence give up more prizes), and I don't know how many of them will need Iris.
Caitlin - Hand refreshing cards are always good, particularly with our oh-so-great Supporter engine right now. Particualrly useful on the turn after a huge Colress to get rid of the dead draw and hopefully get better cards. However, it doesn't work as well on a lategame N, which is where you'd probably want the hand refresh(Bianca, Juniper, Colress are all infinitely superior in that case).
Scoop Up Cyclone - Nice name, but I'm not sure its worth the Ace Spec slot. Primary purpose is to be a non-discarding Max Potion, and I don't know how many decks really need that, considering only Sableye can use it more than once(I imagine it could pull some shenanigans with it though).
The Blastoise set I don't see any particularly interesting cards in(though I will take this chance to say that somebody is going to play Quad Suicune somewhere just because of the Ability and proceed to flop around).
That rounds out what I personally feel are the relevant cards in this deck. The one possibly useful card I left out is Dialga EX, because I can only see it being useful with the help of Porygon-Z, and I don't see Porygon-Z being good enough to warrant building an entire deck around. If you do use it though, you need Dialga EX, Thundurus EX, Porygon-Z to really mill with any degree of reliability. Reverse Edge is rather pricy for what it is supposed to do.
