Defense Grid (Schematic) (Serial Numbered) Price

Updated 2026-07-08

Defense Grid is a Brothers' War artifact that increases the cost of instants and flash spells for all players, with a symmetrical effect that benefits slower, non-instant-heavy strategies. It sees fringe Legacy and Vintage sideboard play as a hate piece against counter-heavy blue decks. The Schematic Serial Numbered printing from The Brothers' War: Retro Frame Artifacts places it in an extreme-rarity category with blueprint-style Schematic art and a limited numbered print run. The thirty-day price movement is minimal, barely positive, reflecting a stable collector market with no significant directional pressure. Seven-day data shows no change. Defense Grid is a niche card with occasional sideboard relevance, and its Schematic Serial Numbered version is primarily a collector holding targeting completionists building the full Schematic Serial set. At this price point, the scarcity premium dwarfs the functional card value. Price stability at current levels reflects a small, satisfied collector base.
