For the purposes of the universe, the first coin flip not only doesn’t matter, it never existed. The magicker himself will claim—and show any amount of supporting evidence—that it landed tails. He will not even remember casting a spell, unless he’d have cast one in this case, too, but for a different reason (if he’d have cast anyway regardless of the toss outcome, he’d get looped, recalling himself making the toss, but not yet casting; or being confused why he recalls casting, but there is no change in the toss outcome).
Time between the toss and casting, when things were different than they are now? What perspective would that need? Looking at the universe from outside the universe?
