After doing a large number of manual wishlist edits, a useful feature would be a drop down added either to the card entry arrow flyout and the card actions drop down.

Card Line in deck
Sideboard->One, All
Add to Wishlist->One, Missing
Add to Inventory->One, Missing, All

Card Actions
Remove
Add Missing to Wishlist
Add Missing to Inventory

The algorithm is already being calculated to determine the amount of missing cards so the function would inherit that variable/value on page load and pass that to the Add to [respective list] -> All function as the amount parameter for the card line. The Card actions drop down is a "Import a list of cards" entry that is created in the background and populated by all the cards + amounts that are determined to be missing.

In my quest to attempt to have my game bankroll itself I've searched high and low for decks that clock in around the sub $200 mark while still being competitive. I figured it might be helpful to post up the results of my searches so that more people could make the jump from casual to competitive if they feel the itch smile I'll edit with updates as I get decks up or you post links to your own entries.
