Here's one I came across IRL today. I thought there should be a forced win, but didn't spot one.
Here's one that doesn't use Charm's special ability at all:
Play all Charms for $2 +buy, play Silver, use all 7 tokens ($22 total)
Bunch of Stonemason overpays:
Stonemason (for 2 more Stonemasons) $4
Stonemason (for 2 Villas) $6 - go right back to buy phase
Stonemason (for 2 Villas) $6 - go right back to buy phase
Stonemason (for Villa + Remodel) $6 (no money left)
Should have 6 Actions (from the Villas) now if I understand the game state right. Stonemasons and Villas are gone.
Play City Quarter and draw 7 cards. Those will be the Copper and either 6 Stonemasons or 5 Stonemasons 1 Remodel.
Play Stonemasons and trash Villas until the Estates are empty.
