I'd like to be able to have the cards that are in my collection showing in my built decks and not just the most recent printing of the card. Is this possible or is this on the horizon?

Seconded. I came to the forum to ask about this exact issue! (As of m19 being added, my battlebond repack cube no longer has the correct rarities shown, and I goofed up my maths! Oops)

Yes :) Alpha testing: Details in decks

THIS IS SO EXCITING!!! Great timing too, lol. The per-line edit button doesn't seem to be working for me on chrome, but I understand it's still in alpha. ^__^:D
