Shade's Breath⁣ - Onslaught⁣ (Uncommon)⁣ [167]

Shade's Breath is a one-mana instant from Onslaught that temporarily turns all your creatures into black Shades, granting them the ability to pump themselves with an additional black mana. This can lead to a sudden surge in power during combat or as a surprise finisher, especially in decks that focus on swarm strategies or have numerous creatures on the battlefield. It's worth noting that its effect only lasts until end of turn, so timing is crucial for maximum impact.
