Ethereal Lantern

Ethereal Lantern is a Rare relic that removes the main drawback of Ethereal cards. Normally, Ethereal cards are exhausted if not played the turn you draw them, which means you lose them permanently. With this lantern, they simply go to your discard pile and cycle back, making them function like normal cards you can choose not to play.

This opens up powerful Ethereal cards that you might otherwise skip during card rewards due to their punishing keyword. The relic pairs well with any deck that uses Ethereal cards but does not want to commit to an exhaust strategy. However, it anti-synergizes with Exile Feather, since you actually want Ethereal cards to exhaust if you are running an exhaust-energy engine.

It also becomes completely redundant if you pick up Eternal Grip, which retains all cards in hand anyway. Priority: build-specific, pick only if you have multiple Ethereal cards and are not running an exhaust build. Skip if you already have Eternal Grip.
