Sure my friend. I'm not a Wizard with that can't post his limited prepared spell list.
The Bastion and his Simulacrums is with Twinned Mind Blank or nondetection spell. Always active.
That's one Twinned Mind Blank on the Cheating One (9th level slot for 8h, as you don't have Mind Blank. Then what do you cast to get Mind Blank on the DMM simulacrum? What do you cast for the remaining 16h of the day? That's 3 uses of 2 Wishes a day.
Contingent Tenfold Fiery Destruction of the Sheared Character Sheet triggers, no more Cheating One.
