Finally figured out how to do it on 2nd players 4th turn after trying for the convoluted, it actually ended up being relatively simple
Stealing from most VPs in 4 turns opening. Both players follow the same first 4 turns.
Turn 1: Draw 4 Coppers and Estate. Play 4 Coppers and buy Nomad Camp, putting it on top of deck.
Turn 2: Draw Nomad Camp, 3 Coppers and Estate. Play Nomad Camp and 3 Coppers, and buy Watchtower and Hamlet.
Turn 3: Draw Estate, (reshuffle), Copper, Hamlet, Nomad Camp and Watchtower. Play Hamlet, drawing Copper and discarding Estate and Copper for +1 Action and +1 Buy. Play Nomad Camp then Watchtower, drawing 5 Coppers. Play 6 Copper, buying 2 Hamlets and a Talisman
Turn 4: Draw Estate, Estate, (reshuffle), Estate, Hamlet, Copper. Play Hamlet, drawing Hamlet and discarding Estate and Copper for +1 Action and +1 Buy. Play Hamlet, drawing Hamlet and discarding Estate for +1 buy. Play Hamlet, drawing Watchtower and discarding Estate for +1 buy. Play Watchtower, drawing Nomad Camp, Talisman and 4 coppers. Play Nomad Camp.
With 5 buys, player 1 buys 1 Hamlet, 1 Watchtower, and 3 Curses, gaining 1 Hamlet, 1 Watchtower, and 3 Curses from the Talisman
Player 2 buys 2 Watchtowers, and 2 Curses, gaining 2 Watchtowers, and 2 Curses from the Talisman
Curses, Hamlets, and Watchtowers emptied
