The Chaos Card is a special card.

Upon activation, Isaac throws the card in front of himself. The card is thrown in the direction Isaac's body is facing, meaning the card will be thrown in the direction Isaac is moving. If he is stationary, it will be thrown in the last direction that Isaac moved.

The thrown card kills anything in its path (including end-game bosses like ??? and otherwise indestructible entities like Stone Grimaces and Retractable Spikes) and gets stuck in the ground/wall after being thrown. The only exception to this is Delirium.

The card can open doors as if a bomb had exploded them, although it can not open any locked doors or open the big door in the starting room of Dark Room and The Chest.

Dark Room and The Chest. The card can extinguish fires and break rocks, potentially revealing Crawl Spaces.

The icon, name and functionality are all a reference to the Magic: The Gathering card Chaos Orb. This card is famous for its unusual effect: the card is flipped from a height of over one foot above the board and all cards it touches as it lands are destroyed.
