Lumengrid Sentinel⁣ - Mirrodin⁣ (Uncommon)⁣ [40]

Lumengrid Sentinel has flying and allows you to tap a target permanent whenever an artifact you control enters the battlefield. This ability can disrupt your opponent's strategy while also providing board control in artifact-centric decks. However, its low toughness makes it vulnerable to removal, so it's best used in synergy with other artefacts for maximum effectiveness.
