Notes and Rules Information for Ob Nixilis, der Widersacher:

• Only the English version of a Magic card receives Oracle updates and errata. View this card in English. (Scryfall note)
• As you cast a spell with casualty X, you choose whether to pay its casualty cost and what the value of X will be. (2022-04-29)
• The copied spell from Ob Nixilis, the Adversary's triggered ability copies exactly what is printed on Ob Nixilis, except its starting loyalty is equal to the chosen value of X and it isn't legendary. The copy becomes a token as it resolves. (2022-04-29)
• You can control exactly one legendary Ob Nixilis, the Adversary and any number of nonlegendary copies of Ob Nixilis, the Adversary. (2022-04-29)
• Casualty N means “As an additional cost to cast this spell, you may sacrifice a creature with power N or greater.” and “When you cast this spell, if a casualty cost was paid for it, copy it. If the spell has any targets, you may choose new targets for the copy.” (2022-04-29)

• You may sacrifice only one creature to pay a spell's casualty cost, and you copy the spell only once. (2022-04-29)
• If you pay the casualty cost of a spell, the copy will resolve before the original spell. (2022-04-29)
• The copy of the spell is created on the stack, so it's not “cast.” Abilities that trigger when a player casts a spell won't trigger. (2022-04-29)
