Rule 201.5
Official source text from the 20 November 2020 Rules release
Some versions of Ikoria™: Lair of Behemoths cards and other promotional cards feature a name other than their own in the upper left corner, with their normal name in a secondary title bar below it. These cards have only the card name specified in the secondary title bar, not the name printed where a card’s name would normally appear. That name is considered flavor text and has no effect on game play.
