Provenance

Where it came from

The Seafloor Oracle was released in early 2018 as part of the Rivals of Ixalan expansion for Magic: The Gathering. As a rare creature card, it was designed to support the set's tribal focus on Merfolk, providing players with a consistent card-draw engine that rewarded them for connecting with their opponents. The card serves as a thematic anchor for the aquatic civilizations of the plane of Ixalan, emphasizing the strategic, research-oriented nature of its deep-sea inhabitants.

The artwork for this specific promotional version was crafted by Simon Dominic, whose contribution helped define the visual language of the Ixalan block. Dominic aimed to capture the mysterious, scholarly essence of the Merfolk, utilizing cool blues and intricate lighting to evoke an underwater atmosphere. Upon its debut, the card was generally well-received by players interested in tempo-based decks, becoming a staple in casual and Commander-format playgroups that favored blue-aligned synergy.
