The 2021 release of Professor Onyx establishes a powerful presence within the Magic: The Gathering trading card game, specifically as card number 83 from the Strixhaven: School of Mages expansion. This foil mythic rare card features the legendary Planeswalker Liliana, bringing her signature black mana philosophy to the academic setting of the Strixhaven universe. Represented by artist Kieran Yanner, the card captures the essence of one of the game's most iconic characters, making it a focal point for collectors who appreciate both narrative depth and mechanical strength. Mechanically, Professor Onyx is designed around the Magecraft mechanic, which triggers whenever you cast or copy an instant or sorcery spell. This ability deals 2 damage to each opponent while gaining you 2 life, creating a consistent stream of value that rewards spell-heavy strategies. As a six-mana Planeswalker with five loyalty, Liliana offers versatile board control through her various abilities. She can reveal cards from the top of your library, force opponents to sacrifice their strongest creatures, or apply relentless pressure through repeated discard and life-loss effects. For collectors, the foil treatment and mythic rare status make this card a standout piece within the Strixhaven set. The combination of high rarity, a beloved character, and a unique mechanical identity ensures that Professor Onyx remains highly relevant in the secondary market. Whether you are building a collection around Liliana or seeking a premium foil card for your library, this release represents a significant addition to any Magic: The Gathering enthusiast's inventory.

Magecraft — Whenever you cast or copy an instant or sorcery spell, each opponent loses 2 life and you gain 2 life. +1: You lose 1 life. Look at the top three cards of your library. Put one of them into your hand and the rest into your graveyard. −3: Each opponent sacrifices a creature with the greatest power among creatures that player controls. −8: Each opponent may discard a card. If they don't, they lose 3 life. Repeat this process six more times.
