Some very interesting cards here. I have to say, I particularly like Reprisal, with perhaps Cyclone as second favourite.
In fact, I would be pretty happy if quite a few of them got into the game itself, which is quite an achievement because I hardly ever think that of community-created cards, my own included. (The funny thing is that I wouldn't actually be too sure about Cyclone actually getting into the game, I just think it's amazing in all other ways).
The thing I have noted though is which cards are in the armory and crucible, while some are still stuck in the forge. While a lot of this is probably timing, it seems strange to me that Winter is right up there (and to a lesser Extent, Enchantress), while Reprisal, Cyclone and Earthchild aren't, despite the fact that they are all very original, have cool implications and applications, and are the closest things to game worthy that I have seen on this forum in a long time.
(Commission I think is the exception, I love that concept too. And Broken Mirror reminds me of neurotoxin, so thats definitely a good thing)
