Shoot the moon - Obtain question

[Your Neighbour]

Hi, for shoot the moon you have to play every heart in your deck in one round, do discards count or only plays?

[Meat Man]

you have to play them! I used the randomizer deck and restarted the run until i got a deck with 8 hearts. Then I destroyed/switch-suit of a few of the cards with tarots until I played an high card with my only heart card

i got this one i think with magic deck, converted like 95% of my deck to diamonds, eventually only having 1 or 2 heart cards in the deck. at that point you just wait until you get them in hand and play it as a throwaway hand and get the unlock.
