Let's say I cast a Wish that undoes a recent misfortune (bullet #10 in the PRD description of Wish). Could my enemy then counter my Wish with a Wish of their own to turn reality back to its original course? What if I then try another Wish to undo that one? And so on until one of us runs out of Wishes, or the situation makes it impossible or irrevelent to continue the Wish duel.
Can I bolster the effect of one Wish by casting another on top of it? For example Wishing for an important NPC to be brought back to life, then a second Wish worded to prevent another being's hostile Wish from undoing the resurrection of the previous Wish? Precautions would need to be taken to prevent assassination by more conventional means, but short of this, can a Wish be used in this way?
