I hear it's now a meme. Has it really been buried away to all but the most nostalgic of Dominion players?
Do folks at least donate their Scout piles to others? Do the potential recipients even accept them?
Do you at least use them as proxy cards? If you lost a few Curses?
Otherwise, if you want to handicap good players, I suppose you can always require them to buy Scouts, else, they automatically can't win, regardless of their score
As part of the "teaching game" newbies automatically LOSE if THEY buy them
