Equivalent cards to “Living Breakthrough” (blue, cares about noncreature spells and magecraft):

• “Stormchaser Drake” (draws cards when targeted by spells)
• “Talrand, Sky Summoner” (creates Drakes when you cast instants and sorceries)
• “Archmage Emeritus” (draws cards for magecraft)
• “Improbable Alliance” (creates Faeries when you draw your second card each turn)

Reason: All are blue and trigger or provide value from casting spells, like “Living Breakthrough.”
