Donate to the Bishops
A stronger golden deck would have been:
Bazaar x2, Bishop x2, Swamp Hag x2, Hunting Grounds
Each turn: Duration Swamp Hag for $3, Play Bazaar, Play Bishop - trashing Hunting Grounds - gaining Duchy, Play Bazaar, Play Bishop - trashing Duchy, Play Swamp Hag, Buy Hunting Grounds
7 VP per turn. If the Duchies run out before the Provinces, replace Hunting Grounds with Gold, Bishop a Bishop and buy a Province.
But is there is time to set up the stronger golden deck before the simple golden deck grabs too many Provinces? Assume you played the same through turn 5. Your deck is Bishop, Silver x3, Copper.
Turn 6: Play Bishop - trash Copper, Buy Swamp Hag
Turn 7: Play Swamp Hag, Buy Swamp Hag
Turn 8: Duration Swamp Hag, Play Swamp Hag, Buy Bazaar.
Turn 9: Duration Swamp Hag, Play Bazaar, Play Bishop - trash Silver, Play Swamp Hag, Buy Bazaar
Turn 10: Duration Swamp Hag, Play Bazaar, Play Bazaar, Play Bishop - trash Silver, Play Swamp Hag, Buy Bishop
Turn 11: Duration Swamp Hag, Play Bazaar, Play Bazaar, Play Bishop - trash Silver, Play Swamp Hag, Buy Hunting Grounds
Turn 12+: Optimal golden deck
You start attacking with Swamp Hag on turn 7. You gain 7 VP on turns 6-11 from Bishops. Hard to say if the Swamp Hag attack is disruptive enough to give the win to this strategy. If you're being attacked, you can transition into the following deck:
Bazaar x3, Bishop x2, Swamp Hag x2, Curse - trashing Curse and Bazaar each turn. 4 VP per turn.
Another golden deck that is resistant to Swamp Hag is:
Bazaar x4, Bishop, Swamp Hag x2, Province, Watchtower - trash Curse with Watchtower, trash Province to Bishop. 5 VP per turn.
