## Description

Baleful Mastery is a rare instant card from the 2021 Strixhaven: School of Mages Promos set, designated by card number 64p. This Magic: The Gathering product features a distinct foil finish that distinguishes it from standard base set releases. The card belongs to the Black color identity and has a mana value of 4, with a base mana cost of {3}{B}. A key mechanical feature allows players to pay {1}{B} rather than the full mana cost; if this reduced cost is paid, an opponent draws a card before the spell resolves. Upon resolution, the spell exiles a target creature or planeswalker.

The 64p designation places this card within the promotional subset of the Strixhaven era, which focuses on special distribution methods rather than the main set checklist.

Collectors frequently track this promo to complete themed collections of Strixhaven-related items or to acquire foil versions of key Black spells. The combination of the promo treatment, the rare rarity tier, and the specific set affiliation makes this card a tangible piece of MTG history. The 2021 Strixhaven: School of Mages Promos release includes this foil Rare card, identified by card number 64p. Baleful Mastery is a Black Instant with mana cost {3}{B} that allows you to exile a target creature or planeswalker.
