Even if you haven’t played the game yourself, there’s a good chance you’d recognize its distinct visuals, particularly Isaac himself. But there’s also The Binding of Isaac, the card game, which launched in 2018 to adapt much of the same experience and tone. Right now on Amazon ahead of October Prime Day, you can pick up The Binding of Isaac: Four Souls Ultimate Collection for just $44.99, more than half off its usual $102.The Binding of Isaac: Four Souls Ultimate Collection$45$12564% off$45$45 at AmazonThis is the lowest price we’ve seen for the collection, and it really has everything — “every retail card currently available,” to be specific, spanning the 2nd edition of the base game (340 cards) and both the Requiem and Four Souls Plus expansions (269 and 98 cards, respectively). What makes this more compelling is the supplementary materials including custom heart and tear tokens, dice, and “tainted” coins, all packaged in a custom treasure chest container.
