Well, I'm not even winning anymore, so maybe if I reveal my solution we can work together to beat stef. The key card is... SCOUT! That's right, Roadrunner. Here you go:
Kingdom: Haunted Woods, Tactician, Counterfeit, Bank, Fortune, Talisman, Highway, Watchtower, Hunting Grounds, Crossroads, Scout, Harem, Masquerade, Council Room, Shelters, Traveling Fair
Start the turn before with a tactician in play. Play Crossroads, 2 Necros, 5 Haunted Woods, and Tactician. Shuffle. Have your opponent’s necropolis via masquerade. Opponent has Tactician in play, plays crossroads and four council rooms, we draw four. Our real turn:
Start with 29 in hand. Play 6 highways.
Play 28 scouts, drawing 112 victory cards.
Play crossroads, drawing 111 scouts and a crossroads
Play 111 scouts, drawing 444 victory cards
Play crossroads, drawing 555 scouts and a crossroads
Play 555 scouts, drawing 2220 victory cards
Play crossroads, drawing 2775 scouts and a crossroads
Play 2775 scouts, drawing 11100 victory cards
Play crossroads, drawing 13874 scouts, a necropolis, and a crossroads
Play 13874 scouts, drawing 55496 victory cards and play necropolis
Play crossroads, drawing 69370 scouts, a necropolis, and a crossroads
Play 69370 scouts, drawing 277488 victory cards, and play necropolis
Play crossroads, drawing 346859 scouts and a crossroads
Play 346859 scouts, drawing 1387436 victory cards
Play crossroads, drawing 1734296 treasure cards
Now it's the buy phase with 3468592 cards in hand, split evenly between victories and treasures. Luckily, all of the victory cards are Harem, so play them all for 3468592 coins.
Now play 999999 Talismen for as many coins.
Now play 734295 banks. We started with 2734295 treasures in play, so we get coins from banks equal to 734295*2734295 + 734295*734294/2 = 2277373353390.
We have 2277377821981 total coins. I still have two cards left in hand though, and they are fortune and watchtower. I double my coins with fortune. Then I buy 2277377821981 travelling fairs. I also have an original buy, a buy from fortune, and a buy from tactician for 2277377821984 total buys. Hunting Grounds are free, so get a ton of them, and trash each with watchtower for 3 estates. Four cards are gained each time and a million copies are gained each time, for a total of 9109511287936000000 gains.
Scout allows me to roughly quintuple my hand size with each crossroads instead of double. It only works because scout is only capable of drawing cards that don't draw more cards, which is what bounds it. The ideas to improve that I have right now are:
- Make opponent play urchin and use outpost/mission to get a larger starting hand. This currently can't even get to 50 cards in hand and so wouldn't make a huge difference.
-Adjust the talisman/bank numbers to be more optimal, probably should be playing some counterfeits too
That might get it over 10^20, but certainly not over 10^25, and we need to be closer to 10^100 to beat stef.
