Heh, I didn't mean to imply anything about your play, or that your victory was undeserved. Reading it here I can see how it can come across the wrong way though - sorry.
I fully understand that "gg" has become a shorthand for "Thanks for the game", but sometimes I still take it to mean "This was a good game." When the latter is wasn't really the case, I sometimes make a joke (hence the smiley!) about it. For me a good game is one that is interesting, well-played by both sides, and reasonably close for most of the way. Here, two of the three weren't the case (not well played by me, and it was basically decided early on).
The reason he couldn't get any $6 hands was because he spent $5 on Lighthouses on turns 6, 8, 9 AND 13.
I certainly didn't play very well but I don't see why this decision in particular is a big deal - Lighthouse has almost the same buying power as all the $5 cards in the game (unless it misses reshuffles, which is a pretty big "unless" to admit), and given that it protects against Mountebank, it's certainly not a lot worse than the $5 cards in the game.
My spice merchant purchase on turn 5 on the other hand...if I want to buy it at all, I should open with it.
