Martyred Rusalka⁣ - Guildpact⁣ (Uncommon)⁣ [12]

Martyred Rusalka is a 1/1 Spirit that can be sacrificed for a mana cost to prevent a target creature from attacking for that turn. This ability provides a layer of control, making it useful in defensive strategies or decks that seek to disrupt aggressive opponents. However, its low toughness means it can be easily removed, so it's best used in conjunction with other creatures to maintain board presence.
