Aggression

ASK FANTASY FLIGHT 

Q: How does Executor interact with Aggression?

A: Aggression is played. Each player now has to choose a unit to sacrifice. Since Aggression is a single effect affecting multiple players simultaneously, the players must individually make choices to resolve the effect, starting with the player who played or executed the effect, with priority then proceeding clockwise around the table. So the dark side player who played Aggression chooses who he will sacrifice first. Note that he is only choosing at this time - the unit he chooses is not sacrificed yet. After the dark side player has made his choice, the light side player does the same. Once all players have chosen who they will be sacrificing, the effect resolves, and all chosen units are sacrificed simultaneously. The Executor may now trigger its reaction once for each sacrificed unit. It must resolve the first of these two reactions in full before initiating the second.
