Relay a random player to the arena and set a property to that player’s name, use another relay and check if their name is equal to the property, and if not relay them again. If yes, re-relay them.
Try using a zone that detects when at least two people are in the zone, and then when it reaches the target of two or more, activates another zone that has a target of 1 player, and then use the relay to teleport the last player out?
I think I might know what you are talking about. Make a player counter. Make the counter track a property. Connect a lifecycle set to player knocked out to a trigger with this block code:
Relays essentially transform a wire pulse and a signal for one person and instead transmit it on the behalf of everyone instead of one person. Or the selected group.
Connect the zone to a counter that tracks a property. Make sure to make the property a number property using a property device and its scope is set to player. Also make sure the counter’s scope is set to player. Make the zone increment the counter. When you need to trigger the duel, connect whatever triggers it to a trigger with this block code:
