Number 4: Numeron Gate Catvari

Number 4: Numeron Gate Catvari was first released in the 2020 set Battles of Legend: Armageddon, an expansion designed to introduce requested cards from the Yu-Gi-Oh! Zexal anime series to the physical trading card game. It represents a specific component of the Numeron network, a powerful deck archetype utilized by the character Don Thousand in the series, centered on the strategic Xyz summoning of these Gate monsters to facilitate a massive direct attack.

The card was designed by the Konami creative team to faithfully replicate the mechanics seen on screen, specifically the ability to double its attack when battling alongside other Numeron Gate monsters. Within the context of the game's competitive history, its release was highly anticipated by players looking to build the Numeron deck, which gained notoriety for its distinct high-risk, high-reward playstyle. The Ultra Rare foil treatment in the BLAR set was chosen to emphasize the card's status as a formidable part of a cohesive, thematic engine.
