Keldo

Keldo was first introduced to the Yu-Gi-Oh! Trading Card Game as part of the original Magician's Force expansion in 2003. Designed as a member of the Gravekeeper's archetype, the card features an effect that allows players to discard it to target and shuffle cards from the opponent's graveyard back into the deck, serving as a tactical counter to graveyard-reliant strategies. The card reflects the broader aesthetic of the Gravekeeper series, which draws visual inspiration from ancient Egyptian iconography and tomb guardians to complement the central narrative of the Battle City arc.

The specific version released in the 2020 Speed Duel: Battle City Box, numbered SBCB-EN127, was included to bolster the Gravekeeper deck lists provided within this self-contained product. Speed Duel is a simplified, faster-paced variant of the game that uses smaller decks and restricted board sizes, and Keldo was reprinted here to provide players with accessible disruption tools. While Keldo has never been considered a centerpiece of competitive play, its inclusion in the Battle City Box was well-received by fans of the series looking to replicate the character-themed decks used by Ishizu Ishtar during the original manga and anime run.
