Chaos Card

The Chaos Card is a Special Card.

Effects

 * 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 downwards.
 * The thrown card kills anything in its path (including end-game Bosses like ??? and otherwise indestructible entities like Stone Grimaces and moving 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.
 * The card can extinguish fires and break rocks, potentially revealing Crawl Spaces.

Synergies

 * Blank Card: Allows for an easy run by allowing unlimited usage of the card.
 * Items such as Habit, 9 Volt, and Charged Baby give more opportunities to use the card since both these items decrease the charge time of Blank Card.
 * The Battery allows Blank Card to be used twice in a room, allowing multi-phase bosses to be killed instantly.

Seeds
GRTC 0GFD (Dropped by clearing the room to the right and down from spawn).

Trivia

 * 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.
