Galvanic Key⁣ - Mirrodin⁣ (Common)⁣ [173]

Galvanic Key is a two-mana artifact from Mirrodin that has flash and allows you to untap target artifact for a cost of three mana and tapping itself. This ability can be leveraged in decks that rely on powerful activated abilities or combo strategies, providing additional utility in resource management. However, its impact is limited by the need for an existing artifact to untap, making it best suited for builds that can maximise its potential.
