Witherbloom Pledgemage

If an effect creates multiple copies of an instant or sorcery spell, magecraft abilities trigger once for each copy created by the effect.

If an effect creates a copy of an instant or sorcery spell, this will also cause the magecraft ability to trigger.

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.
