Eternity Code Card List and Set Guide

Overview

Eternity Code released April 30, 2020, with 101 cards under the ETCO set code: 50 Commons, 26 Super Rares, 14 Ultra Rares and 10 Secret Rares, and no Rares. Four cards also have a Starlight Rare version, and ETCO-EN100, Effect Veiler, is a Starlight Rare only, which makes 105 printings.

98 of the 101 cards were new to the TCG. ETCO-EN005 and EN029 have an earlier 2020 printing in the catalog, and Effect Veiler is a reprint from 2010.

Plunder Patroll gets seven cards, and Nemeses, Ancient Warriors and @Ignister five each. General cards include Accesscode Talker, Ravenous Crocodragon Archethys, Ghost Mourner & Moonlit Chill and Gravedigger's Trap Hole.

Cards and rarities

Eternity Code has 101 set codes, each starting ETCO-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.

Four set codes carry a Starlight Rare on top of their regular rarity, and Effect Veiler is a Starlight Rare only, which is why the rows add up to 105 printings for 101 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.

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 →

Playing it

Three cards in Eternity Code are on the Forbidden & Limited List as of October 23, 2026. Archnemeses Protos, Splash Mage and Linkross are Forbidden.

Eternity Code is a set to pick singles from: most themes get one to five cards, so the general cards such as Accesscode Talker, Ravenous Crocodragon Archethys and Gravedigger's Trap Hole reach more decks than any one theme block.
