Oh... my... god... MACHAAAAAAAAAAAAAAAAMP! It's so bad, but I'm totally making a Machamp deck when it is released.
Cradily seems like one of the most fun Pokemon in a long time.
Tropius seems pretty good. Bianca in a attack seems great in Grass decks, which might be rising in popularity with Genecect EX and Virizion EX. It also one shots Keldeo's with 4 or more energy on them.
Sigilyph with 4 Eviolites, or 3 Rocky Helmets and a Rock Guard, or 4 Silver Bangle's, lololololol
Haxorus isn't actually that bad. OHKO's Plasma Pokemon for 2 energy, and the first attack can do some decent damage.
All the Tool Cards seem fun. Reversal Trigger is my favorite. Since usually the times you need something the most is when your Pokemon gets knocked out. Tool Scrapper is going to be so big in this format.
Iris doesn't seem very good. At most it adds 50 damage, which is always good, but it's a pretty pour use of your supporter if they haven't taken 3 or more prizes. Any Magnezone deck needs to run this though. Your opponent's taken 5 prizes, eh? 2 Iris gg
Caitlin seems horrible. You'd have to have a have a pretty bad hand to get many cards off of it. At least you have no risk of drawing the cards you got out of your hand. It's pretty much reverse Bianca. Got a hand with nothing you can play? Caitlin's good. Got a hand with a ton of playable stuff? Bianca good.
Scoop Up Cyclone doesn't seem very good. Unless you're REALLY attached to your energy cards (no pun intended), Max Potion get's the healing job done a lot better.
Virizion EX might be my favorite card in the set. Hypnotoxic Laser can suck it! Genesect is the most obvious partner for it, but since it's Grass Energy and not Grass Pokemon, you can run it in almost any deck. Even PlasmaBox if you're running Prism Energy. It's attack isn't all that great, but it isn't bad against Keldeo EX.
I don't know what to think of Jirachi EX. Sure, you can Level Ball for a supporter, but then you have 2 free prizes for your opponent. I think I'd rather run Roserade.
If any deck can run the Psychic and Metal Energy for Dialga EX, I want to play it. You can get back Ace Specs. I might be putting this and Prism's into my Klinklang deck once this set comes out. Not sure how good it's second attack would be. If you can get all 4 Plasma Energy out, and a Porygon-Z, and use tons of Max Potions, and your opponent has no way to discard your Plasma Energy, this could be a decently effective mill deck, with a way to take prizes too. It just takes forever to set up. Maybe some Shadow Triads would be a good idea?
Palkia EX is SOOOOO bad. Which sucks, since I like Palkia a lot. Pearl is the only Video Games I played much of at all, so it's sort of sentimental to me.
I want that Shiny Dusknoir RIGHT NOW!!!!!!!!1
This set seems awesome. So many fun idea, and some many actually playable cards.
Whew, long post.
