Archon of the Triumvirate

When a player leaves a multiplayer game, any continuous effects with durations that last until that player’s next turn or until a specific point in that turn will last until that turn would have begun. They neither expire immediately nor last indefinitely.

If a creature is already attacking or blocking when it’s detained, it won’t be removed from combat. It will continue to attack or block.

The nonland permanents will be detained before blockers are chosen. Notably, a creature detained this way can’t block before it is detained.

The two nonland permanents can be controlled by the same opponent or by different opponents.
