The newest headquarters have been around for a few months. You have a different quadrant to toy around with but also a good draw engine though that helps your opponent as much as it does you. Then again, you can control the speed of it, albeit once a turn) and activate whenever you darn well want to.
The minimum is zero but the maximum can get into the double digits. How wild do you want to get with it? Do you want to keep it fairly calm or go for a free card draw each turn?
