What is the name of this Minecraft server?

I've got Minecraft for a long time and wanted to play this one game where you are on such a platform and you have to try to knock the opponent down with a knock back stick. Does anyone know what the server is called?

There are many. If you mean MLG Rush that's GommeHD.net

I know it under the name Aura on Gomme…
But it was a while ago. Possibly. Doesn't that exist anymore…

Restricting a bit could help ^^

Was it a big or a small server? (So from the number of players)
