Sigil of Valor (V.1)⁣ - Retro Frame Artifacts⁣ (Uncommon)⁣ [53]

Sigil of Valor is a two-mana artifact from The Brothers' War Retro Artifacts that boosts an equipped creature's power when it attacks alone, granting +1/+1 for each other creature you control. This makes it an excellent choice for decks that focus on creating a wide board presence, allowing a single attacker to become a significant threat. However, its effectiveness is diminished in decks reliant on swarm tactics where multiple creatures attack together.
