### Unlock Method

 Defeat Isaac as  Eden

**Blank Card** is an unlockable activated item.

## Effects

* Copies the effect of the card or rune currently held by Isaac.
* 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

* Blank card also mimics  and .
* 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. , 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.

###  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:

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

## Synergies

* : 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.
* : 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.
* /: 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.
	+ Only certain cards can be amplified by Tarot Cloth and/or Car Battery.
* +  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 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.
		- allows this to once again be repeated infinitely, as the price will cap at 99 coins, while up to 999 coins can be obtained.
* : Teleports Isaac 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, Ultra Greed or Home floors. Using them here consumes both the Blank Card and the ? Card, spawning an I AM ERROR Shopkeeper.
* : Copies 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

* : All cards are replaced by pills, rendering Blank Card useless unless Isaac also has .
* : 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  and .
* sending Isaac to the I 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.
