y basing the choice of one-boxing or two-boxing off of a quantum coin toss, one could limit Omega's predicting powers from 100% accuracy to a mere coin toss with 50% accuracy.
If you believe in MWI, both outcomes happen, though in different worlds, and Omega knows about both worlds, and stuffs the boxes accordingly.
