Hidden Arsenal 6: Omega Xyz Card List and Set Guide

Overview

Hidden Arsenal 6: Omega Xyz is a 60-card set released July 24, 2012, with codes HA06-EN001 to HA06-EN060. Every card first appeared in the Duel Terminal 6 sets or, in one case, Battle Pack: Epic Dawn, according to the catalog.

It continues Hidden Arsenal 5's archetypes: Vylon (15), Gem-Knight and Gishki (10 each), Laval and Gusto (9 each), Steelswarm (5) and Infestation (2). As its name says, it adds Xyz Monsters: five Secret Rares at HA06-EN050 to EN054, one each for the Gem-Knights, Laval, Vylon, Gishki and Gusto.

TCGplayer has 1st Edition prices for all 60 cards and Unlimited for 55. They are low apart from Daigusto Phoenix: on October 23, 2026 the next most valuable printing was under $4.

Cards and rarities

Hidden Arsenal 6: Omega Xyz has 60 set codes, each starting HA06-EN and printed under the artwork on the right. Where a card comes at more than one rarity, every version shares its code, so the table counts set codes at each rarity and a code printed at two rarities is counted twice.

Each code is printed at a single rarity, so the rows add up to the set's 60 cards. Set completion in TurnZero HQ counts the distinct set codes you own against the set's total, so a card printed at two rarities counts once, with an every-rarity count beside it for collectors chasing each version.
