Do you know these Minecraft game modes?

I wanted to play Minecraft again for a long time now I vaguely remember one of those game modes on a PvP server where you can get items by right-clicking on a shield or by a full chest.
You also jump - mostly with a "kit" - from a floating island and the rest of the world is also limited and floats.

I know a very vague description but maybe someone else knows that haha

SkyPvP. Have many servers, unfortunately mostly pay to win.
