Trapped Teams

Hello guys, and this is my new project for pvp and team work.
Its called Trapped teams.
Main gameplay here is: Teamwork, gathering resources and PVP.
How to play: you need 2 teams and 1 judge.
Every player chooeses his team. blue or green. After they chose it, they go down the tunnel, and go in the fight arena. Then they wait and dont break blocks or gather resources yet.
A player that has noclip like an admin will have to go on the top of the arena. there is a glass woom there called the judge spot.
After he is up there, the players need to hear his go, to start gathering resources, making traps, to prepare for the pvp battle.
After 10 minutes pass, the judge can pull a lever that will cause the wool baricade to drop down. after it has dropped down, the 2 teams are now in pvp battle. Griefing is allowed.
The last team standing wins.
There are also signs at the spawn. that have rules and how to play.

Basic Rules: Dont climb over the bedrock walls.
Dont attack the other team untill the wool baricade has fallen.
Dont break the redstone items. such as pistons and repeaters that cause the wool baricade to drop.
