Library of Leng - Fifth Edition (Uncommon)

Library of Leng allows you to have no maximum hand size, enabling you to hold onto cards that might otherwise be discarded. When an effect forces you to discard a card, you can instead place it on top of your library, preserving your options for later. This interaction is valuable in decks that rely on drawing cards or those that benefit from recurring spells, such as graveyard strategies. However, it does not protect you from effects that exile cards or other forms of removal. Overall, it synergises well with card-drawing engines and can help maintain your hand size in long, drawn-out games.
