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/rune 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 wisps in the middle ring, looking like cards. The wisps spawn Cards when destroyed, and enemies killed by the wisps' tears have a 15% chance to drop a Card. The effect of the wisps and the types of cards they spawn are independent from Blank Card's charge time and the most recently used card.
  • (except in Rebirth)Collectible Car Battery iconCar Battery/(in Afterbirth †)Collectible Tarot Cloth iconTarot Cloth: Uses the card twice. For example, if used with the Two of Hearts/Diamonds/etc. cards it will quadruple whatever amount Isaac has.
    • Car Battery + Tarot Cloth: The card is used 4 times.
    • (in Repentance) Only certain cards can be amplified by Tarot Cloth and/or Car Battery.
  • (in Afterbirth and Afterbirth †) 2 of Diamonds2 of Diamonds + Collectible Restock iconRestock or in Greed mode: 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.
