3V3 Overwatch Tournament with a 1 Time Buy back (meaning they can reenter the tournament once) for $5.
Select Arcade, then select Create Game, go into the game settings, go to Presets and choose 3v3 Lockout Elimination. Change the map settings to only allow Black Forest, Castillo, Ecopoint: Antartica, and Necropolis. No heroes are banned, there is no health pickups on the maps by default, the maps in rotation are all of the arena maps, the 3v3 game mode goes till whichever team wins three rounds, the team that wins a round will have the three heroes they used in that round "locked out", the team that lost the round are still able to use those same three heroes though. If after three minutes and both teams are alive a capture zone appears in the center of the map, after the zone appears the zone will unlock in a few seconds and first team to capture it wins the round.
