Description

Professor Onyx (PSTX-83p) is a legendary Liliana planeswalker promo from the Strixhaven set. Its magecraft triggered ability drains opponents for 2 life and gains you 2 life whenever you cast or copy an instant or sorcery, and it has four loyalty abilities including card selection, forcing sacrifices, and a repeatable discard-or-lose-life ultimate. The card supports a black spells-focused control or midrange role by generating incremental life swing and board disruption tied to casting instants and sorceries.
