    •  ? Card has a unique interaction with Blank Card, noted in the synergies section.

Synergies

• Car Battery/ Tarot Cloth: Essentially uses the card or rune twice. If used with the Two of Hearts/Diamonds/etc. cards it will quadruple however much you have, and if used with a Jera rune it will quadruple the number of pickups in the room.
  • Car Battery + Tarot Cloth: The card or rune is used 4 times at once.
• Car Battery/ Tarot Cloth: Essentially uses the card twice. If used with the Two of Hearts/Diamonds/etc. cards it will quadruple however much you have.
  • Car Battery + Tarot Cloth: The card is used 4 times at once.
• 2 of Diamonds + Restock or in Greed mode: coins can be infinitely generated by buying Lil' Batteries. As Lil' Batteries only cost 5 coins, as long as Isaac starts with at least 11, the maximum of 99 coins can be quickly reached.
  • This cannot be repeated infinitely, as Restock now increases the price of a shop slot every time something is purchased from it. Having 12 coins will very slowly allow you to get to 99 coins, however.
• ? Card: Teleports you to the I AM ERROR room. This will consume both the Blank Card and the ? Card.
  • An exception is when they are used on The Chest, Dark Room, or Ultra Greed floors. Using them here consumes both the Blank Card and the ? Card and spawns an I AM ERROR Shopkeeper.
  • An exception is when they are used on The Chest, Dark Room, Ultra Greed, or Home floors. Using them here consumes both the Blank Card and the ? Card and spawns an I AM ERROR Shopkeeper.
• Rune of Jera: Allows Isaac to copy pickups with every use. This combination can double Lil' Batteries, which can allow for game-breaking combos, due to repeated use of the synergy.
  • Spawning too many items will cause objects to despawn. This can even despawn the End Chest after finishing a final boss fight.

Interactions

• Little Baggy: All cards are replaced by pills, rendering Blank Card useless, unless Isaac also has Starter Deck.
• 0 - The Fool?: The original card will be dropped, and must be picked up again.
• Wild Card: Does nothing if used through Blank Card. Wild Card can, however, copy the last card that was used through Blank Card.
