Umamusume Deck Builder
Compare support card recommendations based on your character, goals, and collection. Use the results as a planning aid, then test promising decks in the Training Simulator.
Struggling With Champions Meeting? Start With Your Deck
You're using meta decks but still losing. You've copied tier lists and spent hours testing combinations, but your win rate has not improved. Many published decks assume specific SSR cards at max limit break - cards you may not have.
Here's What Actually Works
Our deck builder compares your actual cards and suggests combinations to try. Input your collection, select your character, and use the recommendations as a short list for simulator testing.
Common Problems We Solve:
- ✓ "I don't have Kitasan Black" - We'll find alternatives that work
- ✓ "My Speed never reaches 1200" - Compare Speed-focused card combinations
- ✓ "I keep losing to Oguri Cap teams" - Compare PvP-oriented deck options
- ✓ "Which banner should I pull?" - See which card types your collection lacks
How To Read The Recommendations
The tool compares candidate decks from the available support-card data and ranks them by estimated fit for your selected goal. Treat the output as a practical starting point, then verify it against the race condition and current balance state.
You get three recommendations: a primary option, an alternative pattern, and a lower-rarity option when the card pool allows it. Group-type support-card Recreation effects are still under review and may need manual adjustment.
F2P Players: Your R and SR Cards Still Matter
You do not need to ignore lower-rarity cards. R and SR cards at high limit break can be useful when they match your character, training target, and missing stats. The key is narrowing the combinations worth testing.
Your Collection Has Hidden Potential
Tier lists often assume complete collections. This deck builder lets you start from your own card pool and compare combinations that may include lower-rarity cards.
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
Use deck gaps to inform pulls. After comparing your deck options, look for repeated weak spots by card type or role before chasing a card only because it is highly ranked elsewhere.
Example: You might not need another Speed card if your collection already covers that role. A Friend, Stamina, or Wit card could create a more useful next test deck.
Manual Selection vs Deck Builder
| Aspect | Manual Deck Building | Deck Builder |
|---|---|---|
| Time Required | 30-60 minutes of testing | Short candidate list |
| Combinations Analyzed | 5-10 decks through trial | A focused candidate set |
| Synergy Detection | Basic, obvious synergies only | Card-effect and type comparison |
| Character Optimization | Generic builds for all characters | Character-aware comparisons |
| Collection Adaptation | Difficult to adapt tier lists | Works with your exact cards |
| Performance Prediction | Guesswork and intuition | Estimated stat ranges to test |
| Alternative Options | One deck, hope it works | Multiple ranked recommendations |
| Goal Flexibility | Rebuild from scratch for each goal | Instant switching between PvP/Legacy/General |
Frequently Asked Questions
How should I validate the deck recommendations?
Use them as starting points. Training outcomes still depend on RNG, scenario choices, card levels, balance updates, and event handling. For important builds, send the deck into the Training Simulator and compare multiple runs before committing resources.
Should I use "All Cards" or "My Collection" mode?
Use "All Cards" to explore what the full card pool can suggest. Use "My Collection" for practical recommendations you can implement immediately with your owned cards.
Why does the deck builder recommend lower-rarity cards sometimes?
Lower-rarity cards at max limit break can be competitive with higher-rarity cards at low limit breaks. The deck builder considers card effects rather than rarity alone, often surfacing R and SR cards that are worth testing.
How does the deck builder handle different race distances?
The deck builder adjusts recommendations based on your character's preferred race distance. Short-distance runners usually need more Speed focus, while long-distance runners usually need more Stamina and recovery support.
Can I test my deck builds?
Yes! Each recommendation includes an "Apply to Simulator" button that lets you test the deck directly in the Training Simulator for a second pass on likely stat ranges.
What's the difference between PvP and Legacy modes?
PvP mode favors balanced race performance for Champions Meeting. Legacy mode favors pushing selected stats higher for factor inheritance, often sacrificing balance.
How often is the card database updated?
The database is updated from available game data, but new mechanics may need a review pass before recommendations fully reflect them. The live card data currently has no Group-type support cards, so newly announced Group cards, Recreation chains, and special-skill hints are not modeled yet.
Why do friend cards appear in every recommendation?
The borrowed support slot is usually one of the easiest ways to cover a missing role, so recommendations reserve the sixth slot for a strong borrowed option.
Can the deck builder help with specific character builds like "Escape" or "Leader"?
Yes. The deck builder uses character strategy data when comparing deck patterns. Escape runners tend to need Speed-focused options, while Leader builds often need more balanced support.
Is the deck builder suitable for beginners?
Yes. The deck builder is useful for beginners who have not memorized card synergies yet. It provides explanations for each recommendation and helps new players learn why certain cards work together.
