There's several sources of +buy, a metric ton of $2's, and an alt-VP card. This kingdom stands a good chance of 3-piling. As much as I really want to work some sort of Market Square strategy (beggar + watchtower!), I think the safer play is to base your deck around Horse Traders so you can grab Duchies. My intuition is Fool's Gold is a better combo than Tunnel a HT can always buy 2 FG, it takes an extra reshuffle to get the gold from the Tunnel, and I feel like FG can bump to $8 easier.
