I'm pretty sure this is already a thing on Java, and it can surely exist on Bedrock as well. It's simple. You select a gamemode such as sumo, soup, bow, build, melee, gapples, whatever your heart desires, and you 1v1 each other until someone wins. This would be a simple yet effective and beneficial addition for the server, and the player base would likely enjoy such an event being brought to the bedrock community. Thank you, and have a nice day.
