(3★+) |
Increase Velocity with a strong turn of foot when passing another runner toward the back on the final straight. |
Grass Wonder's Unique Skill activates when she is 3rd or lower, and after she has overtaken another runner during the final straight.
The Unique Skill can easily be activated since Grass Wonder will be running as a Late Surger, and can help secure the win during the race's final moments.

|

When training Grass Wonder, use the brand new Unity Cup scenario to take advantage of the new Spirit Burst mechanic. This not only lets you gain more stats than normal, but can also provide useful Skill Hints.
Grass Wonder has an A aptitude on the Late Surger running style. It is best to use this running style when running in races, as this is her best style. Additionally, she has Innate and Potential skills that activate when she is running as a Late Surger, further making this her best running style.
To increase the number of skills you immediately have access to on Grass Wonder, it is recommended to max out her Potential level. This gives you access to some useful skills such as On Your Left! and Position Pilfer.
However, if you do not have the Monies or materials to do so, you can hold back on increasing her potentials.
Since Grass Wonder has 3 Medium Races during her career, we recommend using Legacy that has Medium Sparks if you want to win every race in her career, since she only has B aptitude on this distance.
Legacy and Sparks Guide: Inheritance Explained
Alternatively, you can choose to increase her Mile aptitude instead, as she will be part of your Mile team for Team Trials.
Grass Wonder has to race in the Arima Kinen twice during her career. To increase your chances of winning, try to get at least 400 Stamina before the Classic Year Arima Kinen, and at least 600 Stamina by the Senior Year Arima Kinen.

Since Grass Wonder will be part of your Mile team for Team Trials, prioritize improving her Speed and Power to help her accelerate and catch up as a Late Surger. Getting a Recovery Skill can help lower the Stamina requirements, but it is not required.
If you are only planning to clear a career run with Grass Wonder, then you can aim for lower stat numbers, as the stats above are for Team Trials.
Training Guide: Which Stats to Train?
For Grass Wonder, we recommend a Speed-Wit build consisting of 3 Speed and 3 Wit cards, although you can replace one of the Speed cards with Riko Kashimoto. This helps you maximize training time, while still getting the stats that you need for both her career races and Team Trials.
Alternatively, you can also run a 3 Speed, 2 Power, 1 Pal deck if you are having a hard time getting the required Power and Stamina for Grass Wonder's races.
This deck is for players who are starting out and are still trying to get a feel of the game's mechanics and intricacies. This deck can help you get the needed stats to clear the career, while also providing important skills.
Take advantage of the game's borrowing feature to borrow a powerful MLB SSR, like Kitasan Black. Additionally, if you do not have an MLB copy of Riko Kashimoto (Tracen Academy), it would be better to use another SR Power card instead.
| Recommended Alternative Support Cards | |
|---|---|
| Speed | |
| Power | |
| Wit |
These cards will help Grass Wonder level her needed Stats (especially with Rainbow/Friendship Training), as well as provide some needed skills.
These stats are enough to clear the URA Finale easily, as it provides enough Speed, Stamina, and Power for all of Grass Wonder's career races, especially when partnered with the correct skills. As for the deck, you can run a 3 Speed, 3 Power deck or a 3 Speed, 2 Stamina, 1 Pal deck, with Tazuna Hayakawa as the preferred Pal card.
| Recommended | |
|---|---|
| 9★ Stamina 9★ Power |
|
| 3★ Late Surger 3★ Mile 1★ Medium |
Grass Wonder will need Stamina and Power sparks to help her get the stats she needs for both Team Trial and her career. Prioritize getting Mile sparks to improve Grass Wonder's performance in Team Trials. You can also try to get a Medium spark to push her aptitude from B to A to help in her career, but this is not required.
Afterward, get Late Surger sparks to improve her aptitude and improve her performance.
You can use either your own Veterans, or borrow the ones from your friends. If you do not have Veterans with full sparks, you can go with whatever you have access to.
Grass Wonder is a Late Surger, so she will need acceleration skills to help her catch up later in the race. Good late-race acceleration skills include Furious Feat and On Your Left! are good. The Unique Skill Let's Pump Some Iron! is also great for Grass Wonder, however, its strict requirements make the skill a gamble.
Other than acceleration skills, mid-race velocity skills are also helpful, so taking skills like Professor of Curvature, It's On!, and Mile and Late Surger Corners is recommended.
If you cannot get the recommended skills, you can replace them with similar skills that you have access to. You will just need to make sure that Grass Wonder can activate said skills in a race.
