Provenance

Where it came from

Eidos the Underworld Squire was introduced to the Yu-Gi-Oh! Trading Card Game in the 2021 Brothers of Legend booster set, a release designed to bring long-awaited legacy support and imports from the OCG to the global market. The card functions as a core component of the Monarch archetype, specifically designed to facilitate the rapid tribute summoning that defines the playstyle by providing extra summoning opportunities and graveyard-based recovery.

The artwork and character design reflect the dark, gothic aesthetic established by the Monarch series, portraying Eidos as a spectral servant tethered to the underworld. Created by the Konami design team, the card was received by players as a vital utility piece for deck consistency. Its effectiveness in enabling high-level tribute plays made it a staple for those dedicated to the Monarch strategy during its competitive resurgence.
