BO1 format decks with 15 sideboard cards treated as invalid decks.
- After the update on 7/9/2025, some BO1 format decks with 15 sideboard cards display the message "Invalid Cards: 0"
- These decks can no longer be selected as decks to use in BO1 format
- Before this update, BO3 decks could also be used in BO1.
- From now on, if you want to use the same deck in both BO3 and BO1, you will have to clone it and reduce sideboard cards in BO1 deck, which is a pain.
- Roll back this change immediately.
- If this is not okay, why does the sideboard display have a separator that says "Best of Three Only"?
