Binding of Isaac: Rebirth Wiki

Blank Card is an unlockable activated item.

Effects[ | ]

  • (except in Repentance) Copies the effect of the card or rune currently held by Isaac.
  • (in Repentance) Copies the effect of the card currently held by Isaac. Blank Card's recharge time changes upon use, depending on the card Isaac was holding when he used it.

Notes[ | ]

  • (in Afterbirth and Afterbirth †) Blank card also mimics Dice ShardDice Shard and Emergency ContactEmergency Contact.
  • Using Blank Card does not expend the consumable.
  • Using the Blank Card with a consumable that isn't compatible, or no consumable at all, spends the charge with no effect.
  • If holding more than one consumable (e.g. Collectible Starter Deck iconStarter Deck, Tainted Characters...), only the consumable that is selected will be used. If one of them isn't a card, they must ensure the card is the one selected when activating Blank Card, otherwise the effect won't be triggered.

(in Repentance) Recharge Time[ | ]

Blank Card's recharge time changes upon use, depending on the card Isaac was holding when he used it (except in the case of using the item with no held card). This is a list of the following recharge times the card can have:

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

Synergies[ | ]

  • (in Repentance)Butter!Butter!: As Blank Card is dropped upon usage, the recharge time for it is reset to 4, allowing to use more expensive cards much more frequently.
  • (in Repentance)Collectible Book of Virtues iconBook of Virtues: Spawns card wisps in the middle ring. The wisps spawn random Cards when destroyed, and enemies killed by the wisps' tears have a 15% chance to drop a Card. A wisp is given even if Isaac is not holding a card when the item is used.
  • (except in Rebirth)Collectible Car Battery iconCar Battery: Uses the card twice. For example, if used with the Two of Hearts/Diamonds/etc. cards it will quadruple whatever amount Isaac has.
  • (in Afterbirth † and Repentance)Collectible Tarot Cloth iconTarot Cloth: Invokes the extra effect when used.
    • (in Repentance) Only certain cards gain the Tarot Cloth effect with Blank Card.
    • Car Battery + Tarot Cloth: The effect of the active card is quadrupled.
      • (in Repentance) Only certain Tarot Cloth effects will be doubled again.
  • 2 of Diamonds2 of Diamonds + (except in Rebirth)Collectible Restock iconRestock or in Greed mode:
    • (in Afterbirth and Afterbirth †) Coins can be infinitely generated by buying Lil' BatteryLil' 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.
    • (in Repentance) This cannot be repeated infinitely outside of Greed Mode, as Restock now increases the price of a shop slot each time something is purchased from it. Having 12 coins will very slowly allow Isaac to obtain 99 coins, however.
      • Collectible Deep Pockets iconDeep Pockets allows this to once again be repeated infinitely, as the price will cap at 99 coins, while up to 999 coins can be obtained.
  • (except in Rebirth)? Card? Card: Teleports Isaac to the I AM ERRORI AM ERROR room. This will consume both the Blank Card and the ? Card.
  • (except in Repentance) Rune of JeraRune of Jera: Copies pickups with every use. This combination can double Lil' BatteryLil' 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[ | ]

  • Collectible Little Baggy iconLittle Baggy: All cards are replaced by pills, rendering Blank Card useless unless Isaac also has Collectible Starter Deck iconStarter Deck.
  • (in Repentance)Wild CardWild Card: Does nothing if used through Blank Card. Wild Card can, however, copy the last card used through Blank Card.

Trivia[ | ]

  • This item is a card counterpart to (except in Rebirth)Collectible Placebo iconPlacebo and (in Repentance)Collectible Clear Rune iconClear Rune.
  • (except in Rebirth)? Card? Card sending Isaac to the I AM ERRORI AM ERROR room and destroying both items is a nod to how the combination acting as expected would create an infinite loop, as the two items would attempt to use each other infinitely.
