Secret Slayers Card List and Set Guide

Overview

Secret Slayers released April 3, 2020, with 60 cards under the SESL set code: 40 Super Rares and 20 Secret Rares, and no Commons or Rares.

36 cards were new to the TCG, SESL-EN001 to EN036: thirteen Adamancipator cards, thirteen Rikka cards including Teardrop the Rikka Queen, and ten Eldlich and Golden Land cards.

The other 24 are reprints from 2002 to 2019, from EN037 on, including Upstart Goblin, Solemn Judgment, Block Dragon and Koa'ki Meiru cards.

Cards and rarities

Secret Slayers has 60 set codes, each starting SESL-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 set code has one rarity, so the 60 set codes are also 60 printings. 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.

Set code SESL-EN002

1st Edition market price, October 22, 2026 $9.90

Secret Slayers has no high-priced card. The most valuable on October 22, 2026, was the Secret Rare Adamancipator Researcher (SESL-EN002) at $9.90, just ahead of the Super Rare Snowdrop the Rikka Fairy at $9.78.

Adamancipator Researcher is a Level 2 EARTH Rock Tuner. It can Special Summon itself from your hand while you control another Rock monster, and during your Main Phase it can excavate the top 5 cards of your Deck and Special Summon a Level 4 or lower non-Tuner Rock from among them.

It was new in this set and is printed only as a Secret Rare here.

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 →

Secret Slayers card list

Every set code in Secret Slayers, 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

Two cards in Secret Slayers are on the Forbidden & Limited List as of October 23, 2026. Block Dragon is Forbidden, and Solemn Judgment is Limited.

Adamancipator cards excavate the top 5 cards of your Deck and get stronger with more Rock monsters among them, so the deck is built with as many Rocks as it can hold.
