I would like to track card lists or Favorite cards, separate from Decks. I also want to be able to Favorite a card or quickly add it to a list, while in a match.

Although I grew up in the era of MtG's birth, I never played it. Now, 30 years late, I'm new to MtG so I'm way beyond the age of "memorize every card"- ain't nobody got time for that!

So when I see a super cool new card I've never seen before when playing a match against another player online, I'd like to remember that card. It'd be great if I could Favorite the card with just a simple checkbox (similar to the "View Printed Card") when viewing a card's details in game. Even better, I'd love to add it to a List, and then I can later refer to my different Lists for deck building layer on. It would also let me keep track of cards in particular sets that I'm interested in collecting. If I don't have a specific wildcard to unlock the card, I would be targeting packs to get from the Store.
