Provenance

Where it came from

The Siege Mastodon was released in 2019 as part of the Magic: The Gathering Core Set 2020. Core sets are designed to serve as a foundational experience for the game, balancing accessible mechanics for new players with cards that provide utility in various gameplay formats. As a common creature, the Mastodon was crafted to fill a specific role in the Limited environment, focusing on defensive capabilities and creature typing to support white-aligned deck strategies.

The card features illustration by Igor Kieryluk, an artist noted for his contributions to the fantasy genre and his extensive work within the Magic: The Gathering aesthetic. The design goal was to depict a formidable, armored beast consistent with the high-fantasy themes of the set. Upon its release, it was received as a functional, illustrative piece of the broader Core 2020 ecosystem, valued by players for its role in creature-heavy drafts and its contribution to the set's visual cohesion.
