Maintaining Miss Chance at High Levels (Or Similar Defenses)

From my time spent reading answers here, it seems relatively commonly accepted that in Pathfinder, AC is a weak defense. One claim I’ve seen put forth is that it’s entirely possible to obtain a miss chance that equals or exceeds the protection granted by any level of AC; I find this believable given spells like mirror image, blur, and displacement. I’m currently playing a Pathfinder campaign that’s just hit 14th level where I’ve been making decently heavy use of miss chances in place of AC1, and I’ve personally noticed that some form of sense capable of negating most miss chances (generally blindsight or true seeing) is increasingly common.

What ways are there in Pathfinder for a character to make effective use of miss chances at high levels in the presence of supernatural or magical senses that bypass conventional sources of miss chance? Options for any character are acceptable, though given Pathfinder’s large number of two-thirds casters, I’d especially like to see answers not limited to full casters.

I’m also entirely open to a frame challenge of the form that "miss chance is simply not effective at higher levels in Pathfinder," in which case an answer that elaborates on alternative defenses at high level would be preferred.


1 In case anyone’s curious, I’m playing a silksworn occultist in a War for the Crown campaign. We are using basically all first-party sources as well as Path of War from Dreamscarred Press. The specific issues I’ve been observing are a combination of enemies bypassing miss chances and mirror image as well as either enclosed spaces or highly mobile and proactive dangerous melee enemies.
