Cryptex

Strategy & Gameplay

This colorless artifact from the Murders at Karlov Manor set offers an intriguing blend of mana acceleration and card advantage that rewards players for building around graveyard synergies. At its core, Cryptex functions as a modest mana rock that generates any color of mana while gradually building toward a powerful payoff. The collect evidence mechanic creates an incentive to fill your graveyard with spells, encouraging you to pair this card with self-mill strategies, discard outlets, or naturally card-heavy decks that churn through their libraries. The unlock counters accumulate with each activation, and once you've assembled five counters, you unlock an incredibly powerful effect: sacrificing the artifact nets you three cards while surveilling three additional cards, giving you significant control over both your hand and graveyard composition. Players seeking to maximize Cryptex will want to include it in deck archetypes that naturally generate excess cards in the graveyard, such as Grixis control decks, Dimir mill strategies, or any archetype running Murktide, Expressive Iteration, or similar cards that benefit from a well-stocked graveyard. The flexibility of generating any color of mana makes this particularly valuable in three or four-color strategies where mana consistency matters. Its widespread format legality across Standard, Pioneer, Modern, Legacy, Commander, and more means you can explore this card in virtually any competitive or casual environment. The combination of ramp, filtering, and card draw makes Cryptex a compelling inclusion for players who want a utility artifact that scales throughout the game while rewarding intelligent graveyard management and long-term planning rather than immediate impact.
