Hidden Arsenal 3 Card List and Set Guide

Overview

Hidden Arsenal 3 is a 60-card set released December 2, 2010, with codes HA03-EN001 to HA03-EN060. Every card first appeared in Duel Terminal 3, according to the catalog.

Like Hidden Arsenal 2 it is all foil, 40 Super Rares and 20 Secret Rares, and spreads its cards across eight archetypes: Fabled (10), Genex (9), Jurrac, Naturia and Worm (8 each), Ice Barrier (7), Dragunity (6) and Ally of Justice (4). Nine of its cards are Synchro Monsters.

It is one of the lowest-priced sets in this list. On October 23, 2026 no printing was above $5 in 1st Edition, and none of its cards is on the Forbidden & Limited List.

Cards and rarities

Hidden Arsenal 3 has 60 set codes, each starting HA03-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 →

Hidden Arsenal 3 card list

Every set code in Hidden Arsenal 3, in set code order, with each rarity it is printed at: 60 set codes in all, as listed in TurnZero HQ's catalog on October 23, 2026. Each name goes to that card's page, with today's price for every printing.

Playing it

No Hidden Arsenal 3 card is on the Forbidden & Limited List as of October 23, 2026, so a deck can run three copies of any of them.

The Dragunity Tuners equip themselves to Dragunity monsters and come back out, which is how the archetype builds Synchro Summons; this set has only six of its cards, so it is a starting point rather than a deck.
