True Reversal

True Reversal is the greatest safety net against the magical effects of other 

You touch a creature (alive) or object that has been affected by any spell or magical item effect within its life time. If the target is a creature the spell lifts all negative status effects; reverses all magic aging effects; instantly kills the target if the target is currently alive due to the effects of true resurrection, resurrection, or revivify; banishes creatures to their original plane when conjured to the caster's plane through magic,;and instantly kills the creature if it was created by magic. The spell counteracts any magic caused by a wish spell on the target; reverses all healing and damage effects caused by spells in the last decade; and completely erases any magical curses or enchantments on the target.

When the spell is cast on a magical item (Armor, potions, rings, rods, scrolls, staffs, wands, weapons, and wondrous items) it becomes disenchanted depending on its rarity.  Uncommon magic items (and lower) become a mundane version of their previous state, permanently. Only reversable by another cast of True Reversal. Rare magic items become a mundane version of their previous state until re-enchanted. Very rare magic items become mundane versions of their previous state for one decade or until re-enchanted. Legendary magic items become a mundane version of their previous state for a year or until re-enchanted.

The spell dismisses any illusions present within 50 feat of the target  and unpolymorphs any polymorphed units in 50 feat of the target.The spell completely reverses the effect of all other 9th level as if it were a wish spell. This spell cannot be counterspelled, but can be cast as a reaction to counteract a cast of True Reversal.
