How often would you take a Scout if it came for free on every green card purchase, Duchess style?
This would make a 5/2 split maybe better as you can get an estate to pick up a scout and then a 5 (or another scout if you really want to keep your hands concentrated).
I'm pretty sure that I would not be buying an Estate on turn 1 even if it came with a free Scout, unless there was something *really* good to Inherit.
