I think I just have to be on the wrong path because I can't make it work.
With 6 players, I can get 6 cards into the 6th players 3rd turn, 5 of which can cost up to $4, and one can only be up to $3. If I could find a way around that $3 card to make it $4 I have a solution, but I am not seeing a way to do that.
I know I need +4(5) buys and 1 Talisman, or 3/2, 2/3, 1/4. However, I also need enough money to buy 5, 4, 3 or 2 Grand Markets. Basically, every card I use has to either be a Talisman or give a +buy except one, which only leaves me one slot for a Quarry, but that leaves the GMs at $4 (unless I Bridge them, but that isn't getting me there either), and I haven't generated nearly enough coins to buy them.
I guess my main curiosity would be if you are using more than 6 cards, or if you are using 6 $4 cards, because that would mean I am missing something from my main setup, or it is completely wrong. Also, if you are pulling any crazy shenanigans like what went on in the "buy all the Colonies on turn 5" puzzle, feel free to just post the solution because I am not interested in going there. :-)
