Target Dummies

Target dummies can be made by placing a carved pumpkin on a hay bale. Punching the target dummy will show how much damage you do, but the dummy will never get destroyed unless it is sheared, dropping the materials used to make it. You can put armor and entity heads on it. Placing any entity's armor or head on it will take it's health and the head or armor will drop if defeated, but not destroyed. Hitting a target dummy will send a redstone signal according to the damage inflicted. I hope this idea is considered!
