So i have a fairly simple rules question here. Under the new rules, with all of the changes to the end step, will it be possible for players to receive priority after the beginning of end step effects have resolved, or is it only possible to respond to triggers on the stack? or is it possible to do neither?
I know no one is really a guru on the m10 rulebook, since we dont actually have it yet

, but if anyone has the definitive answer on when players receive priority on end step, it would be appreciated.
