Mastermind's Acquisition (PRIX-77p) is a black sorcery promo from Rivals of Ixalan Promos. It offers a choose-one modal effect to either tutor a card from your library or put a card you own from outside the game into your hand. The outside-the-game option is constrained by tournament rules to your sideboard in sanctioned events, making it a tutor with a sideboard access clause in competitive play.
