A potion generator? I have looked through commands other users have posted, however, I don't really see many potion generators. So I decided to make my own, "The Amazing Potion." The Amazing Potion gives you all good effects ingame currently. That's really all there is to say. So get yourself a commandblock by typing "/give @p command" then press tab and enter. Copy/paste the command into it and power the command block. Then, you've got The Amazing Potion!
