Draft picks are 2 at a time.

Cards that refer to your commander's color identity, such as Command Tower, still function as normal.
Each pack is seeded with 2 commanders, and then all remaining commanders are shuffled into the potential draft pool before packs are constructed. Not all cards will appear in every draft, even when drafting with 8 players. Not all commanders will appear in every draft, even when drafting with 8 players.
