Interesting note from my box of leaf limited. The second to last pack was especially thick. I thought it might possibly have a fifth hit. I opened the pack and saw a block of white thinking that I might possibly have a letter. No, it was two blanks packed together. Plus there were 7 cards in the pack.
I have had this happen with UD Heroes baseball as well. It was kind of funny because I was thinking that some pack searcher at some shop had sought out these packs to come up with blanks and a bunch base.
