So here is a Wacky Packages/GPK cross-over question... Since about 2016, several GPK series have offered a Wacky Packages subset of usually 10 cards that contain past WP titles but with GPK characters. I guess i differentiate these from the GPK parody subsets of different types. What releases have contained these Wacky subsets? I usually try to pick them up on ebay but wonder if I have missed any. I know of the following:
2016 GPK Trashy TV Prime Slime
2018 GPK On, the Horror-ible!
2019 GPK We hate the '90s
Seems like a 2017 gap. As far as I can tell the We Hate the 80's set did not have a Wacky subset, but I may be wrong and just not seem the,
