Defense Grid Price

Updated 2026-09-05

Defense Grid from 8th Edition is an artifact that makes each spell an opponent casts cost three additional mana unless cast during their own turn, a stax piece with persistent Commander play in prison-style and artifact-based strategies. Price data across all measured timeframes shows no directional movement, placing this card in stable equilibrium. 8th Edition was a core set with broad distribution, so the NM Rare float for any card from that product is relatively accessible. The price floor is maintained by Commander demand from players building artifact lock strategies: Defense Grid is a repeatable tax that forces opponents to pass on reactive spells during other players' turns, which is particularly relevant in Commander where instant-speed interaction is common. No breakout competitive catalyst is visible in the near term. This is a stable holding for Commander players who run it and for collectors building white-bordered core set runs.
