Some of the questions in the judge exams have lost their Oracle texts. Dress Down; Bribery; Grist, the Hunger Tide; and Uchbenbak, the Great Mistake don’t have any Oracle text listed in their questions. For example, JudgeApps | Log In has two cards in the question - the text for one shows up fine, but the text for the other card does not show up.
As of last week this issue should be completely resolved. We previously tried to block the art series cards (which Scryfall considers to be a distinct Magic Card with the same Card Name but no Oracle Text), but it looks like that update wasn’t deployed as intended. If you see any further cards with this issue, please reply or email me.
