Pair with Enhanced Awareness to have an on-tap cancel. Underrated card when playing with heroes with little to no deck manipulation or cancellation. There are better protection allies, but none that do what a widow does.
Attack: 1. Thwart: 2.
Interrupt: When a card is revealed from the encounter deck, exhaust Black Widow and spend a resource → cancel the effects of that card and discard it. Then, reveal another card from the encounter deck.
Core Set #75.
