One Command 1.9 - Deadly Snowballs

Hello, I am BootySC. Today I have made a 1 command that makes snowballs deadly! Are you tired of the same old snowballs. Throwing it at that pig 50 times till it dies? I know I am. Thats why I made this! I will spare the detail for it is to much to say.

Recipes------
Armor
Iron(chestplate,leggings,bootys,helmet) + Snowblock = Deadly Snow Armor! (Throw items on ground at different times)

Sword
Ironsword + Snowball = Deadly Snow Sword

Deady Snowball
Snowball + bow + arrow = Deadly snow ball

To make the machine (1.9) do this command /give @p command_block 1 then place it and copy and paste the (MAC:command + v Other:alt + v) command at paste bin here is the link http://pastebin.com/WvBVYN69 when it is in the command block hit the button "Needs Redstone" then run away! The machine will spawn and you can craft the recipes and kill what ever you want!

Give me a diamond. Comment below aswell! Thank you for trying it (Unless you didnt, if you didnt there is no place for you in my heart. </3)
