I was playing with my  friends on minecraft, messing around with some of the new commands and attributes when i found a verry intersting bug, its a Invisable Horse type.... to obtain this horse you will neeed to give your self a command block useing
/give @p command_block  then type this command block "/summon EntityHorse ~ ~1 ~ {Type:0,SaddleItem:{id:saddle}
,Variant:10,Tame:1,PersistenceRequired:1}" it may be hard to see so you might have to spam right click to ride it its not go any potion effects applied to it and the strange thing is that when you add horse armor/ saddle they ant in view.
