Just want to ask about what would the ruling be if your opponent plays too fast?
Player A is the active player and he mentions he is about to attack an objective with X,Y, and Z. Player B wanted to play Force Stasis on X, preventing him from attacking this phase.
Is it perfectly legal to ask Player A to back up one step and allow Player B to play an action before he annouces any engagement or does Player B have to tell Player A to tell him when a certain phase is about to begin and so forth?
