I will consider your Wish DM fiatNope.
I used a Wish well within reason--replicated a 9th-level spell, or performed something like the function called out in the 3.5 version that let you move some number of people to a place you named. And, I worded the Wish to do exactly that, without any wiggle-room.
You, on the other hand, got greedy and attempted to Thanos-snap Wizards out of existence. It's less work for the Wish spell to lead you to believe that's what happened, than to make that happen.
You. Lost.
Your Simulacrum has 2 turns on attack.
And your Wizard doesn't know anything.
