Prohibit Price

Updated 2026-09-15

Prohibit from Invasion is a conditional counterspell that counters target spell if its converted mana cost is two or less. The effect saw occasional Legacy play in tempo builds that wanted a cheap way to stop small efficient spells. Invasion is an older set with a common print run from the year 2000, and while common rarity generally implies abundant supply, a 25-year-old set has seen significant attrition in accessible copies. The 90-day window shows dramatic appreciation, roughly tripling from the prior level, while the 7-day and 30-day windows are flat. This pattern is consistent with a sharp, single demand catalyst in the medium-term that moved the price and has since stabilized. Understanding the specific catalyst, whether a Legacy or Commander deck popularization, is essential before treating the new level as durable. The flat short-term windows suggest the market is consolidating at the new price.
