About this card

Type: Legendary Planeswalker — Liliana
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.

Frequently asked
How can I tell if my Professor Onyx is real?
Professor Onyx is not on our list of commonly-counterfeited cards, but counterfeits exist across every set. Check the print quality and cardstock (real cards have a distinctive blue inner core visible from the edge), the rosette pattern on the back, the security stamp on planeswalker / mythic cards from recent sets, and confirm the collector number and set code match the official Scryfall record. For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.
