Create a Spectral card for every 5 cards destroyed
(Currently 0/5)
Unlock condition: Discover every Spectral card.
I thought it was odd that there was a Joker unlocked for discovering every Tarot and Planet card, but not one of discovering every Spectral card, so I decided to make one. I chose the number 5 here for the pentagram theme, but I can change it to 6 or 7 if that's too strong. In case it isn't clear, this activates for both Jokers and playing cards. (Consumables too I guess, but those can't be destroyed in vanilla if I recall correctly.)
