I for one was late to catch the Chrome Series. After Topps came out with the "All New Series" and "Flashback" I was kind of sick at the ridiculous amount of money needed to make sets with this border and that border they lost me. Yeah it was great to start including sketches and some subsets but if you can't make a set by buying a case then it's just really not worth it. So after Flashback Series 1 & 2 I just stopped with WP.
Then as life has it my son started with Pokemon cards late 2015 and I of course just had to see what has been going on with WP. I saw the Target "Wacky Box" 16 pack and found the Chrome series and I Love it!!! Yeah and although they still have some ridiculous border sets that no normal human will ever collect all of them, I like the clean look and really like the Altered Artwork/Mixed Up Characters. I am working on finishing that set and it's not easy. Heck I have been buying just about all I can and only have a few. I do have 5 sketch cards so completing a set with one sketch from each artist should be easy enough. HAHA!!!
I think it's safe to say you can probably collect the original series 1-16 in half descend condition before ever completing these ANS.
