Professor Onyx, designated as card number 153 in the 2024 Duskmourn: House of Horror Commander subset, is a Mythic Rare addition to the Magic: The Gathering trading card game. Whenever you cast or copy an instant or sorcery spell, each opponent loses 2 life while you gain 2 life, creating a dynamic resource exchange that rewards aggressive spellcasting strategies. The card features a mana cost of {4}{B}{B} and possesses a loyalty of 5, establishing it as a formidable presence on the battlefield. The design of Professor Onyx is crafted by artist Kieran Yanner, whose work defines the visual identity of this subset within the broader Magic: The Gathering universe. As a Legendary Planeswalker, the card offers multiple abilities that allow for strategic depth. The +1 ability lets you look at the top three cards of your library, put one into your hand, and place the rest into your graveyard. The -3 ability forces each opponent to sacrifice a creature with the greatest power among those they control, providing a powerful board-clearing option. Finally, the ultimate ability challenges opponents to discard cards or lose life, repeating this process multiple times to potentially end games decisively. Collectors value this card for its distinct place in the Duskmourn: House of Horror set, which explores a horror-themed narrative within the game's lore. The Commander subset format allows players to build decks around specific legendary creatures or planeswalkers, making Professor Onyx a focal point for thematic deck construction. Its Mythic Rare status highlights its significance in the set's hierarchy, appealing to collectors who seek out the most powerful and visually striking cards. Whether you are building a deck centered around this unique ability or adding to your Magic: The Gathering collection, Professor Onyx offers a compelling combination of mechanical complexity and artistic design.
