Redox, Dragon Ruler of Boulders

Redox, Dragon Ruler of Boulders was originally introduced in the 2013 core booster set Lord of the Tachyon Galaxy as part of a cycle of four powerful elemental dragons. These cards became defining figures in competitive Yu-Gi-Oh! history, known for their ability to summon themselves from the hand or graveyard by banishing other monsters. Their dominance in the game's meta-environment led to significant restrictions and bans, marking them as some of the most influential monster designs in the franchise's history.

This specific printing, OP25-EN016, appeared in OTS Tournament Pack 25, a set distributed exclusively through Konami’s Official Tournament Store program. As a common rarity release, this version was designed to increase accessibility for tournament players during a period when the Dragon Rulers were seeing shifts in their competitive status, reflecting the game's ongoing efforts to balance historical powerhouses with modern card utility.
