Easy Wither V1.0

Welcome to my first One-Command-Block creation!  I created a simple redstone mod that makes wither skeletons drop skulls a lot more frequently!  This was just a test to see if I could get something like this to work.  There will be more to come!  Credit to CrushedPixel for the "To One Command" filter!  Replace the stone block on the bottom at the front with redstone to start the clock.
