Merwyn The Malicious Deck

The Merwyn The Malicious Deck was a deck of four Chocolate Frog Cards, though, despite the name, it did not include the card for Merwyn the Malicious. On 1 August, 1991, Derek met Harry Potter at Diagon Alley. Astounded that Harry had never heard of Chocolate Frog Cards, he offered Harry a choice of one of four decks, including this one, to have for free.
