MTG helper cards are special cards that are used in the game of Magic the Gathering. These cards can be printed on both sides instead of double-faced cards and can be used as substitutes for cards. The helper card must contain the name of the card as well as the type of spell. Sideboarding notes, recipes, and any other information not listed on the card are not allowed. These are optional and should be kept in opaque sleeves
