Hidden Arsenal 4: Trishula's Triumph Card List and Set Guide

Overview

Hidden Arsenal 4: Trishula's Triumph is a 60-card set released April 15, 2011, with codes HA04-EN001 to HA04-EN060. Every card first appeared in Duel Terminal 4, according to the catalog.

It is all foil, 40 Super Rares and 20 Secret Rares, across seven archetypes: Genex (12), Fabled and Dragunity (10 each), Naturia and Ice Barrier (8 each), Flamvell (6) and Jurrac (5). It has twenty Tuners and ten Synchro Monsters, among them Trishula, Dragon of the Ice Barrier, the card in the set's name, which is Forbidden today.

Its prices are low. On October 23, 2026 no printing was above $7 in 1st Edition.

Cards and rarities

Hidden Arsenal 4: Trishula's Triumph has 60 set codes, each starting HA04-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.
