Frozen Egg is a Rare relic that auto-upgrades any Power added to the deck. Powers persist for the entire combat once played, so upgrade value is especially high for this card type. You also save rest-site upgrades for other cards, improving deckbuilding efficiency. The catch: only future Powers benefit — existing Powers are unaffected, so earlier is better.
