If you are drafting with a pod of 8: 20 cards per pack, 3 Packs.
If you are drafting with a pod of 4: 12 cards per pack, 5 Packs.
2 picks per pack
60 card decks (59 or 58 + Commanders) adhering to your color identity
Monocolor legends have Partner. If you begin the game with two commanders, exile a card from your hand unless one or more of them is The Prismatic Piper. (keep in mind Ajani, Nacatl Pariah, Archangel Avacyn, Ral, Monsoon Mage, and other cards like them are NOT monocolored because of their other side! Same is true for cards like Kenessos, Priest of Thassa because of the cost in its activated ability.)
