Library of Leng (5ED-387) is an artifact from Fifth Edition that changes how you discard and removes your maximum hand size. Its replacement ability lets you put cards that would be discarded into your library instead, and it interacts with discard triggers and costs as a replacement effect. It typically serves as a utility card for hand-size management and avoiding graveyard placement while still allowing discard triggers to see the event.
