Who needs it?
Heres a really cool seed i found its -127080298220995964 i will upload some screenshots soon but basicly, it spawns you next to an amazing sand arch, and then is you use it with Risugamis biosphere mod, it gives you an amazing lava lake surrounded by natural obsidian under one of the spheres with massive cave systems around it! Edit:I acuallt found this seed myself, i got a naturally spawned world and used singleplayercommands to get it. its great!
