HE DUEL IS DECIDED BEFORE THE FIRST CARD IS PLAYED.
It’s Time to...
Master infinite possibilities and Obliterate your opponents.
Build Like a Pro. Question Like a Scientist.
Small decisions change everything. Before testing your deck in a duel, test your assumptions.
My deck is good… but sometimes it just feels like luck isn’t on my side.
Maybe the problem isn’t luck, but a lack of understanding of your deck’s real probabilities. Discover what’s hidden between the lines of the math.
“I always swear my bad hand was just bad luck...”
But was it really? The repetition of these ‘accidents’ might be revealing patterns you haven’t noticed yet.
“What’s the real impact of changing a single copy of a card in your deck?”
Sometimes, a single change can shift the entire dynamic. Knowing the true impact of each card is what separates a good deck from a consistent one.
“The perfect combination of cards almost never comes...”
The problem might not be the combination itself, but how it interacts with the rest of the deck. Not every synergy is statistically viable.
“I built my deck based on feeling and YouTube videos.”
Drawing inspiration is great. But making decisions based on data is what gives you a real advantage in the duel.
“I’m not sure if it's better to have 2 or 3 copies of that key card...”
But more isn’t always better. There are objective ways to understand the effect of each variation before leaving it to chance.

Discover How to Become Truly Competitive
Impact Analysis
Analyze, through intuitive graphs, the real impact of the number of copies of a card on your deck's performance. The platform dynamically simulates different scenarios — such as hands with 5 or 6 cards — and generates sensitivity graphs that reveal how percentage variations in the number of copies (more or fewer) affect the chances of drawing the card and the overall performance of the deck. An essential tool to make decisions based on data, not guesswork.
Simultaneously analyze multiple scenarios.
Run parallel simulations of different versions of your deck with variations such as maximum and minimum copies, and hands with 5 or 6 cards. Evaluate, in real-time, the probability of specific groups of cards appearing — for example, a card from group A combined with another from group B — across multiple configurations. Even if the user defines a 40-card deck, the platform tests up to 60 cards in multiple scenarios, using different statistical methods such as Monte Carlo, exclusion/inclusion, and other advanced techniques for in-depth analysis.
Defining Card Groups and Their Compatibilities
Classify each card in your deck according to its function (Starter, Brick, Consistency Card, etc.) and define its compatibility with other cards — high, low, null, or incompatible. This structure allows you to accurately visualize how each card interacts with the rest of the deck, providing a comprehensive view of the synergy between elements and helping to identify potential bottlenecks or optimization opportunities.
Massive Hand Generation and Statistical Analysis of Scores
Generate up to 300 Hands Automatically
Based on the scores assigned to the cards and their compatibilities, the platform calculates:
The individual score of each card;
The score of the relationships between cards;
The total score of each generated hand.
The tool presents graphs on the frequency of card groups (such as Brick, Starter, etc.), average copies per group in each hand, average hand scores, and statistical clustering between pairs of hands. It also generates a distribution table of hands into quadrants such as:
Excellent Hands (all cards above a certain score);
Bad Hands (total score below a threshold);
Intermediate Hands.
The analysis is completed with a probabilistic estimation of win, loss, or uncertainty based on the quality of the generated hands.
No More Theories. Test. Prove. Evolve.
This is not just a deck-building tool — it’s the bridge between intuition and evidence. A platform built for those who take Yu-Gi-Oh! seriously and want to make decisions based on real data, deep simulations, and applied statistics.
