Mnemonic Betrayal Price

Updated 2026-10-09

Mnemonic Betrayal from Guilds of Ravnica is a niche but powerful Mythic that has carved out a specific identity in competitive and Commander markets. The card exiles all cards in all opponents' graveyards and lets its controller cast them until end of turn, creating an explosive single-turn play that generates its mana back through the cards it accesses. This interaction with graveyard-heavy formats has given it persistent demand in competitive Commander and specific Legacy or Vintage combo contexts. Mythic Rares with unique effects that lack functional equivalents tend to hold value better than redundant effects, because there is no substitute available for players who want this specific interaction. Guilds of Ravnica is not a sought-after set for collector copies, but Mnemonic Betrayal's premium as the only printing of this effect means the Guilds version is the only version available. Monitor Commander combo deck development and format metagame shifts for demand signals.
