For some reason Ankh doesn´t have the same property as prettty much every card, because you can buy & use ankh if jokers are full (even of infinite jokers).
If you try this the the card freezes in the middle. When you shut down balatro and restart it the ankh dissapears from the shop (not sure if the used money dissapeared as well).
#Spectral card Ankh not working if Jokers are full and all are infinite.
