Is this somewhere in the puzzle thread? I can figure out how to do it in a 4p game without much difficulty, but not in a 2p game.
I'm sure there's other solutions, but:
Player 1 draws 4 Copper, 1 Estate.
Player 2 draws 4 Copper, 1 Estate.
- Turn 1 -
Player 1 plays 4 Copper and buys a Noble Brigand.
Player 2 reveals 2 Estate, discarding both and gaining a Copper.
Player 1 draws 3 Copper, 2 Estate.
Player 2 plays 4 Copper and buys an Envoy.
Player 2 draws 3 Copper, reshuffles, draws Envoy and 1 Copper.
- Turn 2 -
Player 1 does something; doesn't matter.
Player 2 plays Envoy, revealing 4 Copper and 1 Estate.
Player 1 discards 1 Estate from the revealed cards.
Player 2 puts 4 Copper into his hand.
Player 2 plays 8 Copper and buys a Province.
