What more is there to say, it's an affinity list.  Lists vary based on player's preferences, but they all have the same basic plan: win quickly.  The list has a small update in the sideboard with wear/tear, but nothing else.  If you unsure of what to play in modern, Robots (Affinity) is always a good deck to fall back on.
