Hello people this isn't MY creation but someone elses one (Theredengineer).If you follow my creations you know i make villagers of the challenge games of PopularMMos, and i found this command that works for 1.9.So if you do follow my creations maybe you would like to use this command or combine this one and ijaminecraft's one(1.8 only).If you want some more info or need some help to make this work just leave a comment and look for your answer here in this description.SO FOLLOW MY CREATIONS 'CAUSE MORE FUN IS ON THE WAY.And please leave a comment if you wish that i find more commands (that i did not created) for you and of course i will leave a link to see ALL the creations of the person that really made a command.(i'm sure i'll copy paste more of his commands but here is the theredengeneenr's site:http://www.theredengineer.com/lucky-blocks.html)
