Multiplayer Mods for easy breaking

Are there currently any mods out there for 15._01 in multiplayer that can break obsidian really easily? please suggest some down below!

Blocks are all server sided, so unless the server itself is running the mod, it wont work.

Xray changes the way blocks are rendered. They dont change blocks invisible on the server, or else everyone would have xray.

The only people really willing and able to code hacks that offer such advantages are Team Avolition, and the chances of getting you hands on their hacks is slim.
