This is a small command that you have to copy and paste to get your normal creative experience going. The command does not cause any lag after the command has ran. There will be no clocks created, only standart gamerule will be set.

How to use: first run this command yourself, be sure you are opped and in gamemode 1: /give @p command_block
Place the command block down and paste the command provided as world download (which isn't the world download but a pastebin link).
Last but not least power the commandblock with redstone. For example a redstone torch, button, lever or redstone block.
Functions:
Sets commandBlockOutput to false (no commandblock spam in chat)
Sets different gamerules to a nice setting for creative
Sets time to 6000
Removes the structure when it is done.

Please note that this command only says once in chat that an object successfully summoned. When you see that in chat you know that the command has worked.

It does no harm to use this command multiple times, although it should not do something after it has been used once.

If you found anything in this command that doesn't work please let me notice.
Until next time. Have a nice Coterie time :)
