Diviner's Lockbox is a five-mana artifact that tutors any card straight to hand — once you correctly name the top card of your library, which makes it contingent on setup rather than raw card quality. The payoff is enormous, but the hoop is real enough that it belongs only in decks that can stack the top of the library reliably.

Diviner's Lockbox is a Commander card through and through — the slower pace of the format gives you time to set up the scry or topdeck manipulation needed to crack it, and a tutor-to-hand effect at any card type is genuinely powerful in a singleton environment. In Constructed formats like Modern, Pioneer, or Legacy, five mana for a conditional tutor that requires a correct guess is far too slow and unreliable when faster, unconditional options exist. Oathbreaker sits closer to Commander's tempo, so the same logic applies: playable if your signature spell or planeswalker enables consistent topdeck knowledge, irrelevant otherwise.

Price Context
Current price
$0.07 bulk tier
At $0.07, Diviner's Lockbox is deep bulk — you're paying for cardboard and shipping, not the card. Bulk rares with narrow conditions rarely climb unless a new commander makes the mechanic suddenly ubiquitous, so treat this as a throw-in, not a pickup.
