Types of players
The active player, also referred to as the attacking player, is the player currently taking his or her turn. (Compare with all other players in the game, who are nonactive players.) When more than one player have to take actions or make choices, usually the active player goes first (see APNAP).
A nonactive player is any player who is not currently taking his or her turn. (Compare with the player/players who are currently taking a turn, active players.) When more than one player have to take actions or make choices, usually the active player goes first (see APNAP).
APNAP stands for active player, then non-active player. When an effect lets more than one player do something at the same time, the active player will make and announce all decisions necessary for the action first, then the nonactive player(s) will do the same in turn order, and finally all of the actions will take place simultaneously.
APNAP also applies when the rules (or an effect) require several players to do something that can't all be done at the same time. If multiple triggered abilities are waiting to go on the stack when a player would receive priority, the players will first put their triggered abilities on the stack in APNAP order. Since the stack resolves in reverse order, this means the active player's triggers will resolve last.
