Provenance

Where it came from

Sea-Dasher Octopus was released in April 2020 as part of the Magic: The Gathering expansion set Ikoria: Lair of Behemoths. The set centered on a world defined by its gargantuan monsters and the bond between humans and beasts, introducing mechanics like Mutate to represent the evolution and fusion of these creatures.

The card features artwork by the illustrator Filip Burburan, who depicted the creature with a dynamic, fluid aesthetic that highlights the thematic focus on transformation. Within the competitive community, the card was noted for its efficiency in tempo-based decks, particularly its ability to grant flash and card-advantage mechanics to other creatures on the battlefield.
