Other thoughts in no particular order.
Don't get trapped in the AMF, keep your movement options open.
Wall of Force, Prismatic Wall, Prismatic Sphere remain unaffected by AMF. I would consider Forcecage to also be uneffected.
Artifacts are not effected.
Golems are not effected at least physically. An Iron Golem can still smack them upside the head ... and most PCs are at least as dependent on magic/magic items as you are for defense and offense. Ditto for any other non-Summoned allies.
Never thought about it before but using Greater Spell Immunity on a Summoned Creature should keep it from 'winking out' in an AMF. Obviously select a Summons with strong non-magical attack capability.
Similarly Gate should work to call an ally/allies to help. The calling version is not summoning magic, the creature cannot be dispelled and will be affected by an AMF just like you ... but it won't wink out, just select something again with strong attack ability while otherwise effected by an AMF (i.e. a Solar is still a fairly frightening archer etc. even if it's cleric casting abilities are nerfed considering it will be shooting at something also not benefitting from magic.)
