With the advent of Dark Ages and the Poor House card, it occured to me that it's possible to construct a new sort of moneyless "golden deck" with Bishop-Poor House-Poor House-Crossroads-Province. (Play Crossroads, 2x Poor House, Bishop the Province, buy new province, repeat.)
The question at hand is, how fast can one set this 5 card deck up?
I'm terrible at these things, so this is nowhere near a good solution, but I have it start working on turn 8.
1 Buy Chapel (X)
2 Buy Crossroads (R)
3 XCCCC, trash
4 REEEC, draw CC (reshuffle) X, trash CCEE, buy Poor House (H): deck = CEHRX
5 R, X trash EC, H, buy Bishop (B), deck = RXBH
6 R, B trashing X, H buying H
7 R, H, H, B, R playing H, H, B trashing nothing, buy Province
8 R, B trash Province, H, H, buy Province
9+ Repeat
Someone please improve on this, because I'm sure it's possible.
