Command blocks. Does anyone have ideas?

I'm looking for cool commands for Command Blocks in Minecraft. Do you have any?

Mini-games of all sorts…

What I personally find very cool are menus in Vanilla (ie a box where items are sorted inside, and if you take out an item you will be like Tpt on Minecraft servers with lobby plugins…

A Vanilla Varo for organizers so they just have to download the map…

A complete Vanilla server that looks like it's plugins… (I've done that before)

If you're good, you can also do things like turn yourself into a block and then hide in the form of this block, and someone else has to search, and then click on the "player" on the block…

Unfortunately, I do not know how it works. I'm looking for formulated commands.

A complete vanilla server, which looks like it would be plugins… (I've made schonmal is really nice

I often enjoy playing around with these commands: https://minecraft-de.gamepedia.com/...le_mit_NBT

That was 2017 when I did that… Otherwise there are more recent Miencraft servers like From BehindTheCmd…

Then I did not understand you correctly… So you are looking for finished Commands to paste and use?
