I'm trying to reset a small "skyblock" area. My 1st command block I want to replace the entire area with air (where I'm stuck) then I clone in the starting island after that. I have asyncworldedit, commandhelper, worldguard... I just don't know what I need to make this a reality. Vanilla minecraft clone command only supports 32768 blocks changed at once. The only real way I can figure is multiple command blocks each doing 32k of blocks until all 216k blocks are replaced. There has to be a better way.
