I was wondering if something like this would be practical:
Any Village-Bishop-Graverobber, $6 card
You just play Village, Bishop the $6 card for 1+3 = 4 VP and play Graverobber to get it back.
With this combo it's possible to score unlimited points at 4 points a pop. In comparison, it takes 4 Monument plays to get 4 VP.
You could of course expand on this with a crazy KC-scheme combo, it might make a nice puzzle, how many points can you gain per turn indefinitely with Bishop-Graverobber?
But the question is: Is this a new golden deck that we might see?
