GENERAL
TCG THEORY

Beyond formats.
Beyond games.

Ten players and thinkers examine the foundations of stronger card-game play—from probability and statistics to intuition, original decks, and teaching.

English title and cover treatment are working editorial directions, not final publication data.

What this field is trying to do

Build the foundations
of better play.

General TCG Theory was proposed as a new field for raising players’ fundamental strength. It looks for ideas about card-game skill that can travel beyond one metagame or title—and for bridges from TCG practice to theory and science.

This is not a promise of one universal system. It is an anthology: ten authors approaching misplays, probability, data, simulation, deck construction, intuition, observation, and teaching from different competitive backgrounds.

01

The Original Edition

A ten-essay anthology on stronger play.

Artwork from the Japanese edition

Originally published in Japan as 『一般TCG理論』, an independently edited A5 anthology.

Each author takes a different route through decision-making, probability, statistics, simulation, deck construction, observation, intuition, or teaching. The source edition gives those arguments room to develop through chapter openings, diagrams, and dense multi-column pages.

Ten Essays

Ten approaches to thinking and improving.

  1. 01

    Decision Making

    Against Arrogance About Misplays: Winning Beyond Luck

    Selected results: 4th place, ONE PIECE CARD GAME National Championship / No. 1 final rank, DUEL MASTERS PLAY’S Ranked Match

    Starting from the premise that even elite players make mistakes, this essay asks how to create unfamiliar positions, make the opponent’s best choice harder, and turn relative skill—not luck alone—into wins.

  2. 02

    Probability

    How Card Gamers Can Think About Probability

    Selected results: Top 4, Shadowverse EVOLVE GP Kyoto 2025 / Shadowverse Ratings Cup participant

    Exact win rates are rarely available in real play. This introduction shows how ranges, boundaries, and simple models can still compare choices and connect uncertain information with probabilistic reasoning.

  3. 03

    Reasoning

    How to Build an Argument: Doubt Yourself, Trust Yourself

    Selected results: Level 1 Magic: The Gathering Judge (IJP) / Top 4, 17th Vintage God Challenger Tournament

    Academic writing and deck building share a method: gather information, identify evidence, and test data. This essay explains how to question numbers and articles while still building and trusting your own argument.

  4. 04

    Statistics

    Data-Driven TCGs: When to Trust Statistics and When to Let Them Go

    Selected results: Eight Arena Open cash finishes / Four Qualifier Weekend Day 2 appearances

    Using the MTG Limited platform 17Lands, this essay examines both the power of win-rate data and the limits introduced by bias and context—then asks when statistics should guide a decision and when they should be set aside.

    Working English title and summary
  5. 05

    Simulation

    Freestyle Deck Construction: Monte Carlo Simulation

    Selected results: Top 4, MTG Japan Championship 2021 Season 3 / Top 16, Little Prince Cup Pacific Region

    A Monte Carlo simulation repeatedly models Swiss tournaments from metagame shares and matchup win rates. The gaps between model and result become language for revising format knowledge and deck selection.

    Working English title and summary
  6. 06

    Deck Construction

    Invest in Original Decks

    Selected results: 2021–2022 Magic Pro League / Official MTG broadcast commentator

    Time spent refining an established Tier 1 deck and time spent exploring an unknown deck form an investment portfolio. This essay looks for metagame openings created by bias, and for rules to continue or abandon the search.

    Working English title and summary
  7. 07

    Theory

    Throw Away Half-Baked Theory

    Selected results: Winner, RAGE Shadowverse Wonderland Dreams / Runner-up, Shadowverse EVOLVE Japan Championship 2024

    Theory loses information when experience is put into words, and it does not always lead directly to victory. This essay argues for using trained intuition in routine play and reserving deliberate thought for pivotal branches.

    Working English title and summary
  8. 08

    Observation

    See the Forest Through the Trees

    Selected results: 3rd place, New Capenna Championship / 2022 World Championship competitor

    Between a scripted opening and a calculable endgame lies the position that cannot be fully read. Through MTG examples, this essay defines a broader board sense for prioritizing position, life, and resources.

    Working English title and summary
  9. 09

    Intuition

    Trust Your Intuition

    Selected results: 14th place, 2022 World Championship / 6th place, Innistrad Championship

    Intuition is treated as immediate recognition grounded in experience. By relating fast System 1 thinking to deliberate System 2 reasoning, this essay explores how reflection can correct intuition and strengthen judgment and invention.

    Working English title and summary
  10. 10

    Teaching

    How Do You Teach?

    Selected results: Card Rush Pros (2019–2023) / RAGE esports operations and pro-league launch

    Being a strong player is not the same as being a strong teacher. This essay separates generating options from choosing among them, and considers instruction that begins with the learner’s assumptions rather than hindsight.
