ok iv watchedthe yogscast play it and i thought it would be a good idea to make one so iv teamed up with hungreyhedgehog to make an arena and it would be nice if any one could help first we need a nice wide open space with no mines secondly we need lots of sand and grass and cobbel and thirdly we need cntestents so what do you say guys

the only big problem about the walls is that it causes a ton of lag from all the redstone and sand falling.

AND you have to place all the blocks that got destroyed

Yeah that is a good point

But when the sand comes Down it will only be like 20 blocks high

And I haven't figgered out what il do with the blocks
