I don't have an Elven cutthroat. Bought most of my cards in Alpha, (cutthroat is Beta only) and I've only been buying Flesh golems and earning reward cards ever since.
Congratulations on a couple of great wins.
Have you combined your cards together to make them stronger yet? Or do you prefer to keep them loose as singles?
If you want to play your daily quest and win new cards, its better to combine.
