Hello Aternos! I Would Like To Suggest The Plugin Called "SuperBuildBattle (Spigot)"
Site: https://www.spigotmc.org/resources/super-build-battle.8775/
Desc: Now I Know that there is a Bukkit Plugin that's the same thing but It Would be better to have a spigot-supporting SuperBuildBattle Plugin! (Allows You to compete With friends and judging builds)
