I think I would open remake/hamlet rather than remake silver, with the intention of remaking estates into tunnels.
This. Everyone seems to be advocating HT/Tunnel, but I think Hamlet/Tunnel would work much better, since it draws a card, is not terminal, and allows you to discard UP TO 2 cards. I would probably also get an Ironworks next time I had $4.
I'm not sure. Terminal doesn't really bother me here, as I'm unlikely to be chaining actions anyway. More than that though, if you discard 1 card to Hamlet, you are playing with only a 4 card hand. Discard 2, and it's a 3 card hand. You get no return benefit. With Horse Traders, you also get the late game +buy to pick up a possible tie breaking point, but most importantly, you get a return investment of $3 on three cards. Recognizing that "average hand value" is the summation of all high value cards and all low value cards, it shouldn't be that much of a stretch to expect to hit $5 on the last two cards in hand with some regularity late in the game.
It would be close for sure. I could see reasons to go both ways.. I just have a feeling HT would edge Hamlet on this setup.
