Promise of Loyalty is a rare white sorcery card from the Commander 2021 set in Magic: The Gathering, carrying the card number 348. Designed for multiplayer formats, this card imposes a strict loyalty mechanic on the game board. By paying four generic mana and one white mana, players cast this spell to place a vow counter on one creature they control per player, sacrificing all other creatures they own. Any creature bearing a vow counter cannot attack you or your planeswalkers for the duration of its presence. The card’s design by Sara Winters integrates seamlessly into the Commander 2021 aesthetic, appealing to collectors who appreciate the set's distinct visual identity. As a rare card, it holds a specific place in the Commander 2021 checklist, making it a relevant target for those completing the base set or seeking specific gameplay effects. The five-mana cost positions it as a mid-to-late game strategy, allowing players to secure their board state while disrupting opponents' permanent holdings. Collectors frequently hunt for rare cards from this era to build comprehensive collections or to find specific mechanical interactions. The unique vow mechanic makes Promise of Loyalty a noteworthy addition for enthusiasts of the Commander format, where player interaction and board control are paramount. The 2021 Commander 2021 release includes this rare Sorcery card, which features a multiplayer effect where each player places a vow counter on a creature they control.
