I was thinking about Dominion, and this thought struck me. Abandoned Mine is supposedly the best Ruin, but you'd almost always rather have a Copper over an Abandoned Mine. Ruined Market, however, has the potential to fill the much-needed-+buy gap. In my situation, please pretend that Ruins are in the supply not because there is a looter on the board, but because your gaming group wanted to have them in the supply to jazz things up a little. So, given the choice between Copper and Ruined Market (assuming buying nothing is not an option) which one would you rather buy/buy more often? I included Survivors and Ruined Library because I suppose I could see someone justifying Survivors over either Copper or Ruined Market. Ruined Library is sort of there for anyone who thinks, somehow, Ruined Library is better than any of the other options.
Thanks!
