Sorcellerie — À chaque fois que vous lancez ou copiez un sort d'éphémère ou de rituel, chaque adversaire perd 2 points de vie et vous gagnez 2 points de vie.
+1: Vous perdez 1 point de vie. Regardez les trois cartes du dessus de votre bibliothèque. Mettez l'une d'elles dans votre main et le reste dans votre cimetière.
-3: Chaque adversaire sacrifie une créature avec la force la plus élevée parmi les créatures que ce joueur contrôle.
-8: Chaque adversaire peut se défausser d'une carte. S'il ne le fait pas, il perd 3 points de vie. Répétez ce processus six fois.

Rulings
Some effects instruct you to copy an instant or sorcery card in a zone other than the stack. These copies do not cause magecraft abilities to trigger. However, most effects that do this also allow you to cast the copy, and casting the copy will cause magecraft abilities to trigger.
If Professor Onyx seems familiar, it’s probably because you’ve seen this type of planeswalker before.
If an effect creates a copy of an instant or sorcery spell, this will also cause the magecraft ability to trigger.
Each magecraft ability has a different effect, although they all have the same trigger condition, whenever you cast or copy an instant or sorcery spell.
If an effect creates multiple copies of an instant or sorcery spell, magecraft abilities trigger once for each copy created by the effect.
For Professor Onyx’s second loyalty ability, if an opponent has multiple creatures with the greatest power, that player choose which one to sacrifice. The next opponent in turn order chooses which creature they are sacrificing, then each other opponent in turn order does the same, knowing the choices made before them. Then all chosen creatures are sacrificed at the same time.
For example, if you control Archmage Emeritus and cast an instant or sorcery spell, Archmage Emeritus’s magecraft ability will trigger and you will draw a card.
For Professor Onyx’s last loyalty ability, “this process” is the following: First, the next opponent in turn order may choose a card in hand without revealing it, then each other opponent in turn order does the same. Then all the chosen cards are revealed and discarded at the same time and each opponent who didn’t discard a card (whether they chose not to or had an empty hand) loses 3 life. This all will happen seven times, for a maximum loss of 21 life per opponent.
