Scroll of Rebirth

Scroll of Rebirth is a Legendary relic that recycles exhausted cards by playing one for free every two turns. This creates a constant stream of extra value from cards you have already used up, essentially turning your exhaust pile into a secondary deck. The synergy with Exile Feather is exceptional: if the replayed card exhausts again, you gain energy from it, fueling even more plays.

In exhaust-heavy decks, your exhaust pile quickly fills with powerful cards, making each free replay more impactful. The relic also works surprisingly well with Cursed Cauldron, since exhausted curse cards replayed for free deal x1.5 damage without costing energy. Blood Vow covers the penalty if the free card is your first curse that turn.

The randomness is the main downside, since you cannot choose which exhausted card replays. In a deck with many weak exhausted cards, you might replay a low-impact card instead of a game-changer. Priority: always pick in exhaust builds; strong in any deck that naturally exhausts cards throughout a fight.
