BY FAR...
The worst format I think they could've done, this makes Machamp/Gengar too good IMO, but not as consistent w/out Claydol..
Also THREE sets of Eevees, pretty sure that's never happened before and that's a joke. Also as far as i'm concerned this format is a joke, some decks are just crippled while SPs in essence get better as the loss of Rosy/Claydol doesn't affect them as much as Evolutions(SPs have cyrus for energies and a lot don't use claydol anymore), also isn't felicity's rotated out now? That could hurt Gyarados.
Props to all of you who kept those Mesprits,Uxies, Azelfs and SF Cards(thank god i'm included in that), and to think of it i almost just sold my call energy for next to nothing since i thought they were going to be rotated, good thing i kept those, i expect that to be the most expensive non legend /lv.x.
edit-also dude who posted up on me, Porygon Z LV.X isn't rotated out, it was released in MD and the Porygon Z in the regular sets was pretty crummy too.
