Effects[edit | edit source]

  • Removed in Repentance Mimics the effect of Isaac's held card or rune.
  • Added in Repentance Mimics the effect of Isaac's held card.
    • Does not consume Isaac's current held item.
    • Does not mimic pills.
    • Does not mimic Souls.

Added in Repentance Recharge time[edit | edit source]

In Repentance, 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[edit | edit source]

  • Removed in RepentanceAdded in Afterbirth15►Car Battery Car Battery/Added in Afterbirth †15►Tarot Cloth 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.
  • Added in RepentanceAdded in Afterbirth15►Car Battery Car Battery/Added in Afterbirth †15►Tarot Cloth 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.
  • Added in Afterbirth2 of Diamonds 2 of Diamonds + Added in Afterbirth15►Restock 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.
    • Added in Repentance 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.
  • Added in Afterbirth? Card ? Card: Teleports you to the I AM ERROR room. This will consume both the Blank Card and the ? Card.
  • Removed in RepentanceRune of Jera 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[edit | edit source]

  • 15►Little Baggy Little Baggy: All cards are replaced by pills, rendering Blank Card useless, unless Isaac also has 15►Starter Deck Starter Deck.
  • Added in Repentance0 - The Fool? 0 - The Fool?: The original card will be dropped, and must be picked up again.
  • Added in RepentanceWild Card Wild Card: Does nothing if used through Blank Card. Wild Card can, however, copy the last card that was used through Blank Card.
