Mourner's Shield⁣ - Mirrodin⁣ (Uncommon)⁣ [209]

Mourner's Shield is a four-mana artifact from the Mirrodin set that allows you to exile a card from a graveyard upon entering the battlefield. For a cost of two mana and tapping it, you can prevent all damage from a source that shares a colour with the exiled card for that turn. This card is useful in decks that focus on graveyard interactions and can help protect your life total or key creatures during critical moments.
