This is the FIRST command I have ever made, so if it's a little buggy, don't give me grief, just tell me, and i will fix it.
INSTRUCTIONS:
Plug the command into the command block, and then activate it. This should be compatible in 1.9, but I haven't tested it. Activate the command block, and then there should be a chicken 5 blocks away just floating in air. You need to kill it to get the god sword.
