Lord of the Tachyon Galaxy Card List and Set Guide

Overview

Lord of the Tachyon Galaxy is a 100-card set released May 17, 2013, with codes LTGY-EN000 to LTGY-EN099. 99 cards were new; one had appeared first on a sneak peek card, according to the catalog's release dates.

It starts two archetypes. The Mecha Phantom Beasts (ten cards) are WIND Machines that make Mecha Phantom Beast Tokens and add those tokens' Levels to their own, with Mecha Phantom Beast Dracossack as their Xyz. The Battlin' Boxers (eight) are FIRE Warriors that revive and protect each other and lead to Number C105: Battlin' Boxer Comet Cestus.

It has sixteen Xyz Monsters, more than any earlier set here, and Rank-Up-Magic Barian's Force to turn one into its Number C form. Number 107: Galaxy-Eyes Tachyon Dragon is the Ghost Rare and the one printing in the set above $31.

Cards and rarities

Lord of the Tachyon Galaxy has 100 set codes, each starting LTGY-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.

The 10 Ultimate Rares and the Ghost Rare count again beside their other rarity, which is why the rows add up to 111 printings for 100 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.
