Official source text from the 18 February 2022 Rules release
Some substitute cards can represent any modal double-faced card. These substitute cards include the front-face and back-face symbols on the front face of the card. To use one of them, write in the name of each face of the card it represents. This style of substitute card is found in the Zendikar Rising release.
