Since they're a config option for survival w/e (Takes items out of your inventory) then, survival w/e would be a great idea. Things to make it not over powered: - A 1000 block limit - Cool downs - Maybe a cost per action Thank you and have a great day! =)
Alternatively: https://www.spigotmc.org/resources/...e-supports-multiple-plugins-1-8-1-12-2.51577/ Builder's wand would be better. Allow people to buy them in shop/win them through crates. $100,000 each. 75 uses each. Maximum of 64 blocks per use.
Survival Worldedit is always too Unstable. If you need large amounts of blocks being moved, staff are always there to help.
