Follow up question from this question
So my plan was to use wish to conjure a Fate 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 fate card, and 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.
So if I conjure my fate card, and fail the 33% chance check and can never cast wish again, can I use my fate 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 Fate cards by wishing and repeating, then whenever I fail a wish check, I can throw one fate card at it to recast, and then use the other to generate a second fate card.
My question repeated is: can the fate 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 the its own creation....
or is that too complex for 5e to be worrying about?
