The deck makes money pretty fast (to the point that Account Siphon barely hurts). This update has better defense than V.1 (dropped the pop-ups and caduceus; and added stronger defensive ice).
Important point: dont get too attached to the idea of getting a hit with Info Overload. It's a great piece of ice, but one needs to know which games call for it , and which games are best just dumping the Info Over in archives.
For strategy, see V.1's notes: http://netrunnerdb.com/en/decklist/9707/psycho-overload
