Hidden Arsenal 2 Card List and Set Guide

Overview

Hidden Arsenal 2 is a 60-card set released July 15, 2010, with codes HA02-EN001 to HA02-EN060. Every card in it first appeared in Duel Terminal 2, according to the catalog, so this is the cards' first printing in a regular booster.

It is twice the size of the first Hidden Arsenal and again all foil: 40 Super Rares and 20 Secret Rares. Its cards spread across nine archetypes, the largest being Genex (12), Naturia (10), Ally of Justice (9) and Worm (7), with smaller groups of Ice Barrier, Fabled, Jurrac, Mist Valley and Flamvell. Ten of its cards are Synchro Monsters.

Unlike the first Hidden Arsenal, TCGplayer prices this one in 1st Edition and Unlimited, so the prices here are 1st Edition. They are low: on October 23, 2026 only the two Naturia cards were above $3.

Cards and rarities

Hidden Arsenal 2 has 60 set codes, each starting HA02-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.

Rarity is in the foil rather than the set code, so check it before you price the copy in your hand. Reading the set code and rarity →
