So you draw (or in setup) a guarded card and put its guarding card against it. You then defeat the guarding card and thus the objective is available to claim.... but do you HAVE to claim it straightaway and if you dont what happens?
1: is the guarded card discarded as it wadnt claimed? (Dont think so, would make dol guldur even more impossible if you HAD to claim some of the damaging objectives on turn-1 if they were guarded by an enemy who instantly engaged)
2: does the guarded card sit in staging until somebody wants to claim it?
3: does it sit in staging, and the next revealed encounter card goes against it as a "new" guard?
Appreciate advice.
