Blank Card

Blank Card is an unlockable activated item.

Effects[]

Mimics the effect of Isaac's held card or rune.
- Also mimics Dice Shard and Emergency Contact.

Notes[]

Using the Blank Card does not expend the consumable.
Pills can be mimicked only by Placebo.
Runes and soul stones can be mimicked only by Clear Rune.
Using the Blank Card with a consumable that is not compatible, or no consumable at all, will spend the charge with no effect.

Recharge Time[]

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:

1 room:

2 rooms:

3 rooms:

4 rooms:

6 rooms:

12 rooms:

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

Synergies[]

Butter!: Because Blank Card is dropped upon usage, the recharge time for it is reset to 4, allowing to use more expensive cards much more frequently.
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.
  - This does not apply in greed mode.
  - Having Deep Pockets allows this to once again be repeated infinitely, as the price will cap at 999 coins.
? 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 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.
  - Likewise occurs on Home floors.
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.
Wild Card: Does nothing if used through Blank Card. Wild Card can, however, copy the last card that was used through Blank Card.
