Mastermind's Acquisition

Diabolic Tutor established the tax: four mana to search your library for any card and put it in your hand, exactly double the price of Demonic Tutor for the identical effect, because an unconditional black tutor at two mana warps deckbuilding too hard to print freely. This card matches that cost and that base effect, then bolts on a second mode borrowed from the old wish cycle: pull a card you own from outside the game. That clause is where the design earns its premium. A tutor that only fetches from your own library is priced against every other black tutor; a tutor that can also reach a card set aside outside the deck is a fundamentally different animal, because it lets one card be a library search early and a targeted retrieval later, without either use costing a separate slot. The modal frame is doing the real work here. Charging the full Diabolic Tutor rate rather than the Demonic Tutor rate is what keeps the flexibility honest: four mana to find exactly one card asks the deck to be built around what it fetches, not to slot the effect as generic insurance. The "outside the game" half is not the dead text it reads as at a glance; it is the reason the card exists as its own printing rather than a straight Diabolic Tutor reprint, and it is what the surrounding deck has to be built to exploit.
