I want Cradilly to be good, but right now, I don't see it. MAYBE with Mew EX someone will make a cool deck, but it would require a lot of space and deck specific cards. It at least has potential. Its better to evolve through RC. You don't waste a turn.
It looks like Genesect and Virizion are going to big cards of the set. (Virizion protects you from lasers, that alone makes grass pokemon playable). Might be. Maybe not the better one but I could see it jumping in the meta. I would say around T2 or maybe (depending on the decks in the moment) T1.5 but I don't see it near the BDIF spot.
I also think Jirachi will be huge. The ability near broken. Jirachi's poor HP while giving 2 prizes makes the card terrible. 2 free prizes, its easier to KO than Celebi. Only in KK, it might be good.
For non EXes, I think Haxorus will be big. It keeps plasma pokemon in check and can hold it's own against other stuff with Dragon Axe. This might be one of the few stage 2s that will be worth the effort to bring out. I would like it but stage 2 attackers haven't done good in the format.It also needs fighting and metal energy.
Another stage 2 I think might see play is Porygon Z. It's kind of like the Hydreigon of plasma pokemon. You can't move all your energy around, but it's one of the few things that lets you move special energy, I tried to assemble a Porygon/Virizion/Deoxys/Genesect but space is no where to be found. It had Lugia so that might have been the problem (but if there is no Lugia, there would be no point in running Porygon-Z)
As for the trainers: Silver Bangle = Broken. Finally something to put EXes in check. Combined with Virbank/Lasers, you're doing 60 extra damage from trainers alone (and that's not counting the damage they take if they don't retreat). IDK about this one. Being a tool and with the rise of Garbodor, tool scrapper will be played more. It can be pretty good.
