What I think is playable:
Exeggecute (or however you spell it): Just read the earlier comments. Man that's funny XD Dump it, get it, dump it, get it.
WEAVILE EXEGGECUTE MY GOD XD
Eeveelutions: Believe it or not, now that the Plasma Engine just became so much better, the Eeveelutions couldbe a fast, consistent deck. I've already said that it could be paired with Ho-oh because of energy multitypes and Weavile as a hard hitter to Discard Ho-Ohs.
Mr. Mime: Meh just trollin dem Landos.
Deoxys EX: Obviously having an autopluspower and a two energy attack that can easily decimate a Mewtwo is bad.*sarcasm*
Confagrigus: Yeah actually. I thought of a fun deck. Ok, so you try to set up 4 Confagrigus T2 or 3 then explode them all at once to spread damage. The you can N them to 2 or 1 and try to sweep with an attacker (Lugia, Ho-Oh, Darkrai, Lando, Terrakion EX, something quick preferably)
But no, just play Chandy if you want something to work.
Weavile: Ho-Oh is great with this and spread with a high damage output is nice. Flareon could be nice with this.
Absol: Oh Gaud this is weird. Can take quick prizes
Kingdra: I think this is amazing. Regisnipe for 1 and can hit for a nice amount for 1. Max Potion abuse maaan.
Latios: With Super ER (emergency room duh XD no Energy retrieval) you could spam Luster Purge in Keldeo/Blastoise. Probly not worth it, actually not at all really, but it could be of use.
Raticate: At first it was ok, but when it read AND it just became great. Lugia will benefit immensely from this, but due to its low HP it probably won't see much play. Whoa. 70 HP. Back away this guys a tank.
Kecleon: Omg DIE Mewtwo and Rayquaza. Pretty cool actually
SER: 4 energies back is nice.
Ghetsis: I know you already ya dumb silly sableye hatin thing
Frozen City: Sorry Blastoise Keldeo. Eels could use this, but until it is specified if only from hand maybe not. Really interesting, and seems a lot like Galactic HQ.
Rock Guard: Go away nobody loves you. Tool Scrapper rah
Plasma Energy- The effect is game changing. I mean, colorless energy! WOW.
All the shinies are great and playable surprisingly.
Cryogonal: Starter in B/K? idk sounds like a troll card too.
Electrode: Level Ball searchable,nice draw, so if you have room it could be worth it.
Thundurus EX: We know this already too. Nice attacks, returns special energy.
Klingklang. Oh gaud.
Metagross too broken.
WHOAHOLYSHIZHYDREIGONKILLSTYNAMOS
Latias EX: already know. Pretty much a sigilyph counter and has great coverage. Hits through eviolite and other Latias, and Bouff. Interesting actually. Suckish energy cost, but abuses Blend. Hmmm.....Darkrai/Latias/Hydreigon maybe?
Plasma Ball: getz Plasma Pokemon Nuff said.
Float Stone: Oh joy, my Landorus EX now has free retreat. Could help gothitelle accelgor (less set up) or really any deck with high retreaters.
Shadow Triad: wegotsomeshadycharactersovahere If it wasn't a supporter itd be broken, since it is it makes it less great. Still pretty good for Plasma engine decks, and feeds lugia Plasma. Whoa lol.
Life Essence: Mewtwo wars. Just got a lot. Dumber.
YEAH I KILLED A SIGILYPH. Oh crap no prize card >:U
Id play any other Ace Spec over this though. Dang that limit.
FA JUNIPER YEWEYE(Aofujospdi0spzxujrf0 v[psdmuh9bjobpvszl[fu0[pl;fsivo xkml
Max Potion why.
Empoleon/Landorus/Terrakion so expensive
Tool Scrapper why you ruin people's fun D:
