Teferi's Moat + Sandwurm Convergence + Painter's Servant Combo

All permanents on the battlefield (Teferi's Moat and Painter's Servant naming the same color on the battlefield).

Because Sandwurm Convergence prevents creatures with flying from attacking you, and Teferi's Moat prevents creatures without flying from attacking you (as they're all the named color due to Painter's Servant), no creatures can attack you.

You can't be attacked
