Combines the OG Luckyblock mod with ChanceCubes for 1.16.5, for easy installation.
The server pack contains an island floating above the void. There are placed several luckyblocks from Alex Sochas' mod, and chance cubes by TurkeyDev around the island.
This opens up for a fun luckyblock skyblock pvp session. Set everyones' spawnpoints at different locations before beginning. Every round is unique, just download the map again from the serverpack to play on a fresh island. Huge chance cubes will cause huge events, such as hundreds of tnt exploding in your face, or boss arenas spawning. Or perhaps you're lucky enough to be covered in diamonds?
