In a 2-player Colony game, I once pulled off:
Madman
Madman
Madman
King's Court
King's Court
Bridge
Bridge
Bridge
King's Court
Bridge
King's Court
Goons.
So, to recap (or make sense of this mess): Madman x3 gives me 26 cards in hand and 4 actions
Action 1: KC-KC-Bridge-Bridge-Bridge
Action 2: KC-Bridge
Action 3: KC-Goons
By the time the dust settled, I had 16 buys, every card on the board was free, and my buys gave me an additional 16 VP in tokens
