This is a follow-up question from this question: Can I use Divine Intervention or Wish to regain Wish?
My plan was to use wish to conjure a "The Fates" card from the deck of many things. This would trigger the repercussions of wish, and there is a 33% chance to lose the power to cast it ever again. However, I do get the card "The Fates"; if the spell failed, then I don't suffer the repercussions, and I still have my 9th-level spell slot to try something else with.
If I conjure my Fates card, and fail the 33% chance check and can never cast wish again, can I use my Fates card to have never cast wish in the first place?
This effectively would give me back my spell slot and allow me to cast wish again.
If this is possible, I can put my devious plan into action: get 2 Fates cards by wishing and repeating, then whenever I fail a wish check, I can throw one Fates card at it to recast, and then use the other to generate a second Fates card.
Can the Fates card undo the casting of a spell to regenerate the spell slot that was used to create the card?
The Fates. Reality's fabric unravels and spins anew, allowing you to avoid or erase one event as if it never happened. You can use the card's magic as soon as you draw the card, or any other time before you die.
To clarify, my confusion comes from the almost paradoxical effect. Say I get the card from wish, but are never able to cast it again, and I use the card to undo its own creation… Or is that too complex for 5e to be worrying about?
