Cryptex is a compact artifact that rewards careful graveyard management and timing. Tap Cryptex and collect evidence 3 to add one mana of any color and place an unlock counter on it. That steady accumulation of unlock counters is the engine here. The foil shown is in poor condition and may have surface wear or corner dings, but the printed ability and play pattern remain unchanged for tabletop use.

Once Cryptex has enough unlock counters you can sacrifice it to surveil 3 then draw three cards. It reads like a slow build with a strong payoff. Use it in decks that can fill the graveyard reliably and that value incremental advantage over an entire game rather than a single burst. This card fits Murders at Karlov Manor’s investigative theme by turning evidence into card advantage.
