Change in decks with cards not in collection
With today's update there has been a change in the way MTGA displays decks with cards not in your collection. Previously they were grouped together at the bottom with a large dark red wildcard symbol and a shaded deck art if you did not have enough wildcards to craft them, but if you did have enough wildcards they would appear with your fully owned decks with a smaller wildcard symbol and the regular deck art, and they would be sorted with those decks based on when you saved them. Now all decks with uncollected cards are grouped together below the fully owned decks but above the decks with errors (wrong format, not enough cards, etc.), and with the lighting and wc symbol to indicate that you have enough wildcards to craft them.
See the images below for examples.
The 40 WC deck includes the first 15 white rares I could find that I had 1 or 2 copies of.
The 1 WC deck is 4 Eiganjo, Seat of the Empire and 56 Plains.
As you can see in one of the images, I currently have 9 rare wildcards.
