i got this idea from the common corrupted computer house idea
so in short there is only one team that can't build and they spawn inside a build (any one makers chooses) and the build will try kill all the players by building evented bricks to kill the players like it will build a brick turret, a lava pit, or just temporally trap players in a brick cube
so the build wins by killing all the players
but the players will win by destroying a special sphere brick that has health, the build will have 1 of this brick at all time it will never go to 2 or 0 or any other number than 1. the players have to kill that brick the brick will have a lot of health (like the Bose player types). the build can move the sphere in a different area away from the players to protect itself but it can only move it any time after 90 seconds
