I know the game is still new, but what are people thinking about for selling or trading of decks?

I’ve got 30 decks so far for myself (got out of destiny and used trade credit to get two of the deck boxes).

I’ve registered all the decks so far, got lucky with a Horesman Deck and a few decks I’d love to try as well.

I noticed some COOL site that has stuff for sale has various decks but they seem ASTRONOMICALLY over priced and I’d like to just get a feel for what others might think would be a good way to either sell or trade these decks?
