Just played my first game with the expansion! 2-player against my housemate. I clinched the win by playing a Gizmo on Pilgrims, scoring a 16/7 card and a 12/6 card, using Ambassador's ability to spend $4 to advance a crown for each Pilgrims play and the Gizmo play. At first I thought I was $2 short, but then I looked over and had $2 on my Beggar. Felt good to have exactly enough money to win.
Beggar was also great for nabbing a Gizmo in the first place. I had no money of my own, so nothing for the Zombies to take. But I could use the $2 on my Beggar to buy the Gizmo.
