Rulings
4 official rulings, in the order Wizards published them.
- 2021-04-16
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.
- 2021-04-16
If an effect creates multiple copies of an instant or sorcery spell, magecraft abilities trigger once for each copy created by the effect.
- 2021-04-16
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.
- 2021-04-16
If an effect creates a copy of an instant or sorcery spell, this will also cause the magecraft ability to trigger.
Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.
