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.

The anthology brings together approaches to misplays, probability, data, simulation, deck construction, intuition, observation, and teaching. The English edition includes Nathan Steuer’s “Mastering Hand Reading: A Universal Skill Across All TCGs.”

Ten Essays

Ten approaches to thinking and improving.

01
Decision Making
“Arrogance for Misplay” and How to Win without Luck
Morinin · @morinin_duelmas
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.
02
Probability
An Introduction to Way of Thinking for Card Gamers Facing Probabilities
Yua · @as_your_real
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.
03
Reasoning
The Way to Assemble the Way of Thinking Doubt Yourself and Believe in Yourself
Denchu · @den0120
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.
04
Statistics
An Encouragement of Data TCG Trusting Statistics and Discarding Statistics
Yamabe Kafka · @yamabekafka
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.
05
Simulation
Deck Selection Freestyle Monte Carlo Simulation Edition
Amal · @amalgam_sv
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.
06
Deck Construction
Invest in the original deck
Mori Noriyuki · @kushiro_mtg
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.
07
Theory
Throw Away Your Half-baked Theories
Surre · @surre_sv
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.
08
Observation
Can Know the Forest for the Trees
Yoshigoe
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.
09
Intuition
Trust Your Intuition
hikiyamamatsuri · @hikiyamajasmine
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.
10
Teaching
How Do You Teach?
Amu · @4mutaaaN
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.
