Starting today (Dec 6, 2022) I cannot play any of my wild decks, because they wrongly claim that they contain missing cards.
In ‘My Collection’, when I open a wild deck and select one of the ‘missing’ cards, some of them say “this card is not in your collection” while others say “This card cannot be used in standard” — which of course is irrelevant, as it’s a wild deck.
I double-checked that it is indeed a wild deck, that it didn’t somehow auto-convert to standard. Because of this, the game is currently unplayable for me.
This issue appears to have been introduced today (Dec 6, 2022). As recently as yesterday, none of these problems existed.
