As far as I can tell,  if you add a card and don't select a specific printing... even if it's like the ONLY version of a card you own it doesn't register it as a specific printing.  If that makes sense... you have to click on the printing and pick it EVERY TIME.

Just curious what I did wrong or if this is a site issue.

So I added The Brothers War Urza deck to my decks and had all the cards set to specifically be the version included in the deck.   Later on in the evening I added the Kamigawa Neon Dynasty Commander decks to my inventory.  After I did this some of the cards in the Urza decklist changed to the Neon Dynasty versions.   

Any idea why this would have happened?

Are the etched-foils gonna be added?   Or am I completely missing it.  Ive been differentiating my etched by marking them as both foil and promo for the time-being.

Thanks

Basically this would be like creating a deck, except cards put in a list arent counted as being in a built deck or deck idea.  This could be useful for creating reference lists or maybe noting the location of cards in binders or boxes.  It's a simple idea that could be really helpful for collection tracking.
