Reaper Spawn Egg

Put this command in a impulse (orange) command block un-conditional and needs redstone.

Same reaper just in a spawn egg. For more information visit The Reaper, an ancient post. That was a great mob and I have put it now into a spawn egg. A ghastenstien spawn egg may come if I can work out the bugs.
