Ok So Let Me Explain How This Works.

Enter Player Name - Here enter username of the player you want head of in the glass. (watch video for clarification its short.)
Unique Scoreboard Name - Here enter any unique scoreboard that will be used for randomizing drops.
Unique Scoreboard For Crafting - here enter a unique scoreboard that will be used for crafting your lucky block
Enter Item For Recipe - here enter items of minecraft.without Minecraft: (e.g. bone,diamond)
Enter Init Command - These commands will run only ones when machine gets installed (scoreboards will get automatically added so dont use this for adding scoreboards)

Now in these 20 areas enter your commands without / (these command will run randomly when your lucky block is broken giving player random stuff) you can use mcstacker to make commands if you dont know how minecraft commands works. http://mcstacker.bimbimma.com/

ones all areas are filled press Get Command button and a command will Popup on the big textarea just copy that with cntrl + c and then enter in your minecraft world and paste it in a command block and power it with redstone and thats it, now throw those 2 items on ground that you used in Enter Item For Recipe area and they will give you your luckyblock place egg and whenever anyone break it random stuff will popup (stuff that you filled in those 20 textareas)

You are allowed to make any lucky block and take credit for it as long as you credit this page at a visible location of your post/video
