7 rulings from Wizards of the Coast
- 16 April 2021Each magecraft ability has a different effect, although they all have the same trigger condition, whenever you cast or copy an instant or sorcery spell.
- 16 April 2021If an effect creates multiple copies of an instant or sorcery spell, magecraft abilities trigger once for each copy created by the effect.
- 16 April 2021If an effect creates a copy of an instant or sorcery spell, this will also cause the magecraft ability to trigger.
- 16 April 2021If you somehow control two Veyrans (which would be poetic), you casting an instant or sorcery spell causes abilities to trigger three times. A third Veyran (less poetic) causes abilities to trigger four times, and so on.
- 16 April 2021Some 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.
- 16 April 2021Veyran's effect doesn't copy the triggered ability; it just causes the ability to trigger again. Any choices you make as you put the ability on the stack, such as modes and targets, are made separately for each instance of the ability. Any choices made on resolution are also made individually.
- 16 April 2021Veyran, Voice of Duality's last ability causes each of your magecraft abilities, including Veyran's own, to trigger an additional time.
