Maze of Millennia Card List and Set Guide

Overview

Maze of Millennia released January 18, 2024, with 85 cards under the MZMI set code, MZMI-EN000 to EN084: 57 Rares, 16 Super Rares, 11 Ultra Rares and one card the catalog lists as a Common, Earthbound Release. MZMI-EN000, Junk Warrior, is a Quarter Century Secret Rare only, and five cards also have a Collector's Rare version, which makes 91 printings.

39 cards were new to the TCG, MZMI-EN001 to EN039: Flame Swordsman cards (EN001 to EN010), anime cards such as Clorless, Chaos King of Dark World and Bonfire, Earthbound Prisoner and Earthbound Servant cards (EN027 to EN034), and Harmonic Synchro Fusion.

The other 46 are reprints from 2002 to 2023, including Junk Warrior, Jet Synchron, Ancient Chant, Altergeist and Rescue-ACE cards and Triple Tactics Thrust.

Cards and rarities

Maze of Millennia has 85 set codes, each starting MZMI-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.

Five set codes carry a Collector's Rare on top of their regular rarity, which is why the rows add up to 91 printings for 85 set codes. 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.
