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.

Professor Onyx (PRM-90088) is a Legendary Planeswalker — Liliana promo from Magic Online Promos. It has a Magecraft triggered ability that drains life whenever you cast or copy an instant or sorcery and a +1 that mills three and lets you choose one to hand at the cost of 1 life. Its negative loyalties include forcing opponents to sacrifice top-power creatures and a potentially repeated discard-or-lose-3-life ultimate that can drain up to 21 life.
