Umamusume Deck Builder
Get AI-powered support card recommendations based on your character, goals, and collection. Our algorithm analyzes thousands of simulations to find the optimal deck for your needs.
Can't Beat Champions Meeting? Your Deck is the Problem
You're using meta decks but still losing. You've copied tier lists, spent hours testing combinations, but your win rate hasn't improved. The problem? Those "perfect" decks require specific SSR cards at max limit break - cards you probably don't have.
Here's What Actually Works
Our deck builder analyzes YOUR actual cards and finds the combination that wins. Not theoretical perfection - real decks you can use right now. Input your collection, select your character, and get a deck optimized for your specific situation in 10 seconds.
Common Problems We Solve:
- ✓ "I don't have Kitasan Black" - We'll find alternatives that work
- ✓ "My Speed never reaches 1200" - We'll show you the exact card combination needed
- ✓ "I keep losing to Oguri Cap teams" - We'll optimize for PvP meta counters
- ✓ "Which banner should I pull?" - We'll identify your collection's biggest gaps
Why Players Trust Our Recommendations
10,000+ decks optimized monthly. Our tool runs thousands of simulations per deck to find combinations that actually work. While other guides show you what's theoretically best, we show you what's achievable with your cards.
The difference? We test every possible combination from your collection, considering character aptitudes, stat caps, and skill synergies. You get three recommendations: Best (optimal performance), Alternative (different strategy), and Budget (using lower rarity cards).
F2P Players: Your R and SR Cards Can Actually Compete
Stop believing you need all SSR cards to win. A well-optimized deck with R and SR cards at max limit break often outperforms random SSR cards at low limit break. The key is finding the right combinations - something that takes hours of testing manually.
Your Collection Has Hidden Potential
Most players use only 20% of their cards effectively. They follow tier lists that assume perfect collections, ignoring powerful synergies between lower-rarity cards. Our optimizer evaluates EVERY card you own, finding unexpected combinations that rival meta decks.
Real Examples from F2P Players:
- • SR Make Debut deck reaching 9500+ evaluation
- • R-card speed deck hitting 1150+ Speed consistently
- • Mixed rarity deck winning 60%+ in Champions Meeting
- • Budget inheritance deck producing blue factors
Smart Pull Recommendations
Don't waste gems on cards you don't need. After analyzing your deck, we show exactly which cards would provide the biggest improvement. No more pulling blindly because a card is "SS tier" - you'll know if it actually helps YOUR specific situation.
Example: You might not need that new SSR Speed card if you already have 3 good Speed cards. But that SR Friend card on rate-up? It could be the missing piece that makes your entire deck work. We'll tell you exactly what to prioritize.

Frequently Asked Questions
How accurate are the deck recommendations?
Our deck builder achieves 85-90% accuracy in predicting final training outcomes. The recommendations are based on thousands of Monte Carlo simulations that account for RNG variance, ensuring realistic expectations rather than best-case scenarios.
Should I use "All Cards" or "My Collection" mode?
Use "All Cards" to see the theoretical best deck and understand what cards to aim for in future pulls. Use "My Collection" for practical recommendations you can implement immediately with your owned cards.
Why does the optimizer recommend lower rarity cards sometimes?
Lower rarity cards at max limit break can outperform higher rarity cards at low limit breaks. The optimizer considers actual performance rather than rarity alone, often finding hidden gems in R and SR cards.
How does the deck builder handle different race distances?
The optimizer automatically adjusts recommendations based on your character's preferred race distance. Short distance runners get speed-focused builds, while long distance runners receive stamina-heavy compositions with appropriate recovery skills.
Can I test my deck builds?
Yes! Each recommendation includes an "Apply to Simulator" button that lets you test the deck directly in our Training Simulator for detailed performance analysis and stat predictions.
What's the difference between PvP and Legacy optimization modes?
PvP mode maximizes race performance with balanced stats and essential skills for Champions Meeting. Legacy mode pushes individual stats to extreme values (1200+) for superior factor inheritance, often sacrificing balance for specialized greatness.
How often is the card database updated?
Our database syncs with the latest game data within 24 hours of new card releases. We continuously update card stats, skills, and event information to ensure recommendations reflect the current meta.
Why do friend cards appear in every recommendation?
Friend cards are essential for skill point generation and provide unique training bonuses not available from other card types. The 6th slot (friend support) offers the highest impact on overall training success.
Can the deck builder help with specific character builds like "Escape" or "Leader"?
Absolutely! The optimizer recognizes character-specific strategies and adjusts recommendations accordingly. Escape runners get speed-burst focused decks, while leaders receive balanced builds with positioning skills.
Is the deck builder suitable for beginners?
Yes! The deck builder is perfect for beginners who haven't memorized card synergies yet. It provides detailed explanations for each recommendation, helping new players understand why certain cards work well together and accelerating their learning curve.
