Lifesmith⁣ - Scars of Mirrodin⁣ (Uncommon)⁣ [124]

Lifesmith allows you to gain 3 life whenever you cast an artifact spell, provided you pay an additional mana. This ability can be leveraged in decks that focus on artefacts, particularly in formats where life gain is beneficial for sustaining your board presence. However, its limited stats (2/1) make it vulnerable to removal, so it's best used in strategies that can protect it or maximise its life-gaining potential.
