EDH-Cube (Multiplayer) (Cube)

This is my first cube. A Multiplayer-EDH-Cube; it started out in summer 2016 when i took apart a couple of my EDH decks. The cube is far from optimized because it consists mainly of cards i had already at home or acquired by some casual trading. For the time being it will remain more of a budget-cube.

Draft (4-5 Players):
1) Commander Packs first (The "Sideboard"): 1 pack/player
still not sure about pack size; 5-8 cards maybe?
2) Normal Packs (also contain some possible commander-options and a few draft-matter cards)
not sure about the pack size; maybe 5 packs each with 12 cards
3) Non-Basic Lands: 1 pack/player
very budget

Deck: so far we tried 66 cards + 1 Commander

Feel free to comment and make suggestions, i would be happy :D
So far I am not sure about pack sizes and the amount of packs everyone should receive.
I also consider adding the C16 partner commanders (1 of each colour combination --> 10), they would probably go into the regular packs.
I also think about adding three colour cards, but I am not sure if that would be wise.
