Proxies are not allowed as substitutes for cards that their owner has damaged intentionally or through negligence. • The card is a foil card for which no non- foil printing exists. Players may not create their own proxies ; they may only be created by the Head Judge who has sole discretion as to whether the creation of a proxy is appropriate . When a judge creates a proxy, it is included in the player’s deck and must be denoted as a proxy in a clear and conspicuous manner .

Spoiler: 3.5 Checklist Cards Official checklist cards are used to represent double -faced cards in the sets that contain them . Only official checklist cards may be used to represent double- faced cards in a deck. The use of checklist cards is required if a player has double- faced cards in their deck and is not using compl etely opaque sleeves. 19 If a player uses a checklist card to represent a double- faced card in their deck, then all copies of that double -faced card in the deck must be represented by checklist cards, and any copies of that double -faced card in a hidden zone are considered to not exist for purposes of determining deck legality. Each individual checklist card used must have one (and only one) of the items checked. A checklist card is only used while the card it represents is in a hidden zone. The card represen ted by a checklist card is not a playable Magic card until the checklist card has been placed in a public zone. Multiple checklists cannot be used to represent a single copy of the actual card. For each checklist card used, the player must have a copy of t he actual card available, though they are not considered sideboard cards and are not presented to their opponent
