This is one of the best buffon packs I ever got, and it was the very first one I opened that run… and at that point, neither of them did anything (since it's abandoned deck). Blueprint was still appreciated but I thought it was a fun coincidence that technically, neither of these would help right after selecting.
Finished the run, was low stakes anyways but wanted to share the situation.
I think I paired it with a really basic joker (think greedy?) which makes for some good flushes early
