Minecraft servers like BastiGHG?

I'm looking for a server similar to BastiGHG's, which is unfortunately not public. On the server you should be able to do challenges with several people… Thanks in advance

I think it will be rather difficult to find such a server because Banko writes and installs these plug-ins. Nevertheless, you could search for plug-ins on the Internet (or program some yourself) to make a server like this.

Go to Brenntasa.net this is a Challenger Network where you can master the challenges together with other players. The server is in 1.15.2
