so I was looking up cube craft records and found non for most obsidian placed in a single match so I started this live stream and attempted to give it a try and we ended with a little over 2310 obsidian that's a estimate btw because the cube is 11 long 6 wide and 35 blocks high plus a little from around it that we placed and don't worry I checked with cube crafts rules and one of them is that quote "Teaming is allowed when every remaining player agrees to it ." so don't yell at me in the comments I looked it up before hand any ways the people who helped me are ZSkull221 {Ahmed097 even tho he tried to kill us} and ZynVice who died early on but still helped anyways here's a link to the video we do have a few failed attempts tho
