I want to thank you for this thread, as it's helped me a great deal. In a couple of days I've gone from using the unupped deck to having a fully upped deck of this and am starting to build a gold farming deck. I did have to sell off a few upgraded cards I already had in my hand to do it, though, whereas before I've always tried to keep all upgraded cards, no matter whether I had a use for them right away or not. That's too slow, though, and it's better to build up a specific deck for getting electrum faster, then re-buying/upgrading the cards you want.
I'd like to suggest a couple of changes to the OP, though. It says that the Shard of Gratitude heals you for 5 points a turn, whereas now it's only 3.
It also says that Divine Glory has no permanent control, yet it's got 12 Explosions.
