Not sure if this is a new idea for the website, but I think it would be kool to see how many views your deck has had by other users, just a simple counter. And when searching through All Decks, have a column with views? It would kind of promote a popularity filter, over time people would be able to filter a column to see which decks have had the most views etc. Ultimately a "want" rather than a need idea but with a purpose behind it.
