I have made up a rough scarecrow deck finally, and played it earlier today, it is still quit slow atm, but hwne it gets going it is powerful.
Some cards I reckon I'll need to help it along are:
Reconstruct(not sure whether or not I have anymore of these)
another Reaper King, Painter's Servant x3, Scarecrone.
And any blue cards that aid artifacts.(doesn't have to be blue but would be prefered)
