How are multiple triggered abilities from different players handled when they all trigger at the same time?

When multiple triggered abilities from different players trigger at the same time, they are placed on the stack in Active Player, Non-Active Player (APNAP) order. In this system, the abilities of the active player (the player whose turn it is) are placed on the stack first, followed by the abilities of non-active players, which ensures a consistent and fair resolution of effects based on turn order.

This method is critical in maintaining the structure of gameplay, as it allows the active player to resolve their triggered abilities first, ensuring that they have the first opportunity to react to or respond to the abilities of the other players. It promotes clarity and efficiency in resolving multiple effects, particularly in situations where the timing of abilities may significantly impact the game state.

The other methods mentioned, like simultaneous resolution, random order, or preference by players, do not adhere to the established rules and could introduce confusion and inconsistency in gameplay. Therefore, understanding the APNAP order is essential for handling triggered abilities correctly in a multiplayer environment.
