NAME TAG OF DOOM! by syedgamer

This adds in a rule to the game where any mob named "Killer" will instantly be killed! You'll receive a stack of glowing name tags named "Killer" to give you a start. Use the name tag by right-clicking a mob and they'll die!!! Be sure to NOT destroy the purple (repeat) command block or else it won't work! The repeating command block contains the game rule to kill any mob named "Killer" nearby.
