Designed by Sveta Pikul, this card targets collectors who appreciate the intersection of strategic gameplay and iconic superhero narratives. As a white mana cost of four generic mana and one white mana, it offers a distinct tactical option for decks built around the mono-white color identity. The card’s mechanism revolves around the concept of vows, a thematic element deeply rooted in the Marvel Super Heroes setting. Upon casting, each player assigns a vow counter to one creature they control while sacrificing all others. This creates a dramatic board state where the remaining creatures are protected from attacking the caster or their planeswalkers, provided they retain the counter. This effect provides a powerful defensive utility, appealing to players looking to control the pace of the game during critical moments. For Magic: The Gathering enthusiasts, Promise of Loyalty represents a unique piece of the Marvel Super Heroes Commander expansion. The subset focuses on legendary creatures and commanders, making this Sorcery a valuable addition to any collection of themed cards. Collectors often seek out cards from this era to complete their set of the Marvel Super Heroes release, valuing the artistic contributions of Sveta Pikul and the strategic depth of the Commander format. Whether you are building a new deck or expanding your library of rare cards, this product stands as a notable entry in the 2026 Magic: The Gathering catalog. Its role in enforcing loyalty through mechanical constraints offers both narrative flavor and functional gameplay. As you evaluate your options for adding to your Magic: The Gathering collection, consider the strategic implications and collectible nature of this release.

Each player puts a vow counter on a creature they control and sacrifices the rest. Each of those creatures can't attack you or planeswalkers you control for as long as it has a vow counter on it.
And so was born the Fantastic Four! And from that moment on, the world would never again be the same!
