Blank Card

{{:{{{1}}} | {{{1}}} | {{{2}}} }}
**Blank Card** is an unlockable activated item.

## Effect

* Mimics the effect of Isaac's held card or rune.
	+ Does not consume Isaac's current held item.
	+ Will not mimic pills.

## Synergies

* Starter Deck/Deep Pockets - Allows Isaac to choose between 2 different effects to copy.
* Car Battery - 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.
* Allows to create a variety of useful effects by copying cards and runes:
	+ III - The Empress - Damage bonus for second and all subsequent activations is higher than the initial and slowly increasing.
	+ VI - The Lovers / V - The Hierophant - Spawns a great amount of hearts.
	+ VIII - Justice - A stronger version of The Book of Sin
	+ XIX - The Sun - Allows a repeatable 4 charge full healing, a The Necronomicon effect and a full map reveal. Can also be combined with Sharp Plug or Habit for both infinite health and infinite The Necronomicon effect.
	+ Chaos Card - Allows the player to instantly kill any monster every 4 rooms, including late-game bosses.
	+ Credit Card - Allows the player to take Shop, Devil Room and Black Market items for free across multiple floors.
	+ File:DLC Indicator.png Dice Shard - Works as a 4-room recharge The D6 + D20.
		- File:DLC Indicator.png Dice Shard + Sack Head + Glitter Bombs - Glitter Bombs make pickups, Sack Head turns pickups into sacks, sacks have a chance of containing batteries but contain more pickups, and unused pickups can be re-rolled into more sacks.
	+ Algiz - A much stronger version of the Book of Shadows.
	+ Perthro - Works as a 4-room recharge The D6.
	+ Ehwaz - Works as a 4-room recharge We Need to Go Deeper!
	+ Jera - Allows the player to duplicate pickups which in combination with batteries can allow for gamebreaking combos.
	+ File:DLC Indicator.png ? 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.
	+ 2 of Diamonds - Doubles Isaac's coins every 4 rooms.
		- File:DLC Indicator.png With Restock or in Greed Mode, coins can be infinitely generated by buying Little Batteries. As batteries only cost 5 cents, as long as Isaac starts with at least 11 cents, the maximum of 99 cents can be quickly reached.
	+ File:Afterbirth† Indicator.png Black Rune - Allows Isaac to consume unwanted pickups and items frequently, gaining a lot of free stat upgrades and blue spiders/flies.
* A Card Against Humanity: Allows rooms to be repeatedly filled with Poop.
	+ A Card Against Humanity + Lil Larva: Destroying all the poop will spawn a large number of blue flies.
	+ A Card Against Humanity + Petrified Poop: The poop has a high chance to spawn Pickups.

## Interactions

* Little Baggy - Renders the Blank Card useless since all cards and runes are transformed into pills, unless the player also has Starter Deck.

## Trivia

File:DLC Indicator.png Using Blank Card while holding XIX - The Sun unlocks the Blinding Baby, a co-op baby that activates the effect of XIX - The Sun upon death.
