Please give verification some how instead of just I think so because. I know tons of people on here can read the rulebook for better than myself (especially since I no longer own any of them).
Situation:
Gandalf, Powerful Guide,
Erland, Dale Counselor are at a site. Gandalf has
Radagast's herb bag on (of course) erland is fighting lets say sauron (for the sake of argument). He exerts Erland to grab
Strength of Spirit and immediately plays it to prevent the exertion he just added to grab
strength of spirit. He removes the exertion and does it over and over adding exertions on
Powerful Guide and burdens on the Ring-bearer until Sauron is dead.
Question is I guess can the exertion be prevented from Erland from an event (spell) that he is grabbing from that exertion? If so that is pretty awesome. Basically Erland exerts grabs that event from discard pile (basically heals) then
Powerful Guide can trigger off that spell being played. Seems pretty OP to me, but hey this is LotRTCG and expanded after all.
Please let me know and please add something from the rules that verifies the fact that you can respond to the exertion with a card you are grabbing from your discard pile. I can see how that would work if
strength of spirit was in your hand, but being able to grab it from your discard pile and preventing the exertion from an action that grabbed that card seems a bit wrong. Once again if this is legal that is so awesome and hats off to those who have thought of this before hand

Edit:Nevermind just read
Strength of Spirit with the auto-link. Clearly he can't prevent that exertion cause it is no longer about to happen it already has. If I am wrong on this let me know.
Guess you could exert erland twice to grab 2 from discard pile and then use those 2 events (spells) to grab 2 other spells, but not nearly as powerful as the other way

. Grnted the other way was limited by exertions to
Powerful guide and Burdens you could add but both of those coulda been overcome as well.
Anyway let me know which way is correct, but im almost certain the correct way is in the edit.
Thanks,
NK
