Helper card
A helper card is an optional substitute for a double-faced card, introduced with Zendikar Rising.[1] On the front side you can write, the back side is a regular card back.
Description
When playing with double-faced cards, either the traditional transforming ones or modal double-faced cards, it's important that your cards are indistinguishable from one another. To accomplish this, you can use opaque sleeves, and you can also use these helper cards.
To use a helper card, you must have the actual double-faced card in your possession. Write down the name of the card you're representing, along with any other information visible on the actual card. You can't use helper cards to jot down sideboarding notes, or anything not found on the card. During the game, if the card is in a public zone, swap in the real card. If it's in a hidden zone, use the helper card.
