Mastermind's Acquisition card art
Mastermind's Acquisition is a four-mana unconditional tutor that finds any card in your library or sideboard — in Commander that means any card you own, period, since the format has no sideboard restriction on what you can register. K'rrik, Son of Yawgmoth cuts the effective cost to two life and two mana, and pairing it with Walk the Aeons in the wish pile turns a single cast into a repeatable extra-turn engine with no deck slots sacrificed.

K'rrik, Son of Yawgmoth converts every black pip into two life paid, so Mastermind's Acquisition effectively costs two generic and four life — fast enough to slot into turn-three or four kill sequences and flexible enough to fetch whatever piece the current board state demands.

Commander is where Mastermind's Acquisition earns its slot: the wish clause isn't restricted to a sideboard, so any card you physically own becomes accessible, turning it into the most flexible tutor in the format for decks that can afford four mana. In Legacy, it competes against Demonic Tutor, Vampiric Tutor, and Imperial Seal at half the cost or less, and the wish upside rarely justifies the extra mana — it doesn't see play there. Modern and Pioneer are similarly hostile; four mana for a sorcery-speed tutor without an immediate board impact is too slow in those formats. Oathbreaker mirrors the Commander dynamic — the wish clause is legal and potent — but the smaller deck size makes raw tutors more redundant.
