Plains Above, Deepslate Below

This lovely Minecraft seed cuts to the core of what Minecraft has always been about for me. Above ground, you'll find a gorgeous plains biome upon which to build your home. It's not entirely flat either, so if the earlier seed was a bit too dull for you, there are some nice hills here on which to build. And just below as you spawn, you'll find the entrance to a massive cave system which allows you to descend all the way to deepslate without having to mine a thing.
