How is "open" defined? Buy before the first shuffle?
2xMandarin, Inn
I'll define open loosely as any cards you gain on the first 2 turns OR (if you use more than 2 turns) any cards gained before your first real end of deck shuffle. So you could open 10 Mandarins for instance.
And you could "open" Curse if an opponent buys Ill-Gotten Gains.
This should make it possible to come up with something creative.
The one I had in mind was:
P1 buys Noble Brigand, you reveal Estate + Copper
P2 buys Noble Brigand, you reveal Estate + Copper
You buy Vault with 5 Copper, draw Estate, reshuffle, draw Vault + 3 random cards, during your next turn you play Vault, discard everything and buy GM for $6.
