Upcoming Characters and Support Cards
Although the numerous stamina Recovery skills Grass Wonder (Healer) has access to may look tempting, this will make training her a little more difficult, as you will need to rely on Hints and Events to get your Speed skills. Pull for Grass Wonder (Healer) if you really like Grass Wonder as a character.

Similar to the original, Grass Wonder (Healer) should also be run as a Late Surger. This is due to her access to some Late Surger skills like A Small Breather (and its upcoming upgrade Relax), Sharp Gaze, and Late Surger Savvy ◯.
Additionally, her Unique Skill activates when she is located toward the back of the pack, which is easy to do as a Late Surger.
To help her run in this style, make sure to improve her Late Surger aptitude from A to S using Legacies.
Grass Wonder (Healer) will need Speed and Power as a Late Surger so she can overtake her opponents and catch up to the front of the race. Having high Speed boosts her top speed, while having high Power improves her acceleration.
Stamina is still an important Stat to improve, however, as she needs to win the Arima Kinen twice in her career. Getting her Stamina to around 400 for the Classic Year and around 600-700 for the Senior Year should be enough, especially with Grass Wonder (Healer)'s access to multiple Recovery skills.
It is important to get Grass Wonder (Healer)'s Potential level to the max level as this unlocks Relax, the upcoming direct upgrade of A Small Breather. If you do not have the resources for it, however, then try to get it to at least Level 3 so you can get access to the skill Cooldown.
Grass Wonder (Healer)'s career consists of Mile, Medium, and Long races. Similar to the original Grass Wonder, it is recommended that you improve her Medium aptitude to A using Legacies so that you will have an easier time winning her career races.
It is also possible to increase Grass Wonder (Healer)'s Long Aptitude from A to S for the purpose of using her as a Long runner in Team Trials. Thanks to her access to Long recovery skill Cooldown, it is possible to turn her into a competitive Long runner without the need to get her Stamina as high as the usual minimum Stamina requirement.

Grass Wonder (Healer) is a Late Surger just like her original version. Thanks to her access to multiple recovery skills, you can focus instead on increasing her Speed and Power, which will help her in overtaking her opponents. Afterward, increase her Stamina, before improving her Wit and Guts in that order.
It is important to note that if you cannot reach the stats recommended above, you can instead aim for a similar stat distribution. You can then compensate for the missing stats using skills. Additionally, if you are only planning on clearing a career run with Grass Wonder (Healer), then you can aim for lower stat numbers, as the stats above are a baseline for Team Trials.
We recommend a 3 Speed, 2 Power, and 1 Stamina deck, which should give Grass Wonder (Healer) the stats she needs for her races. Although only having one Stamina card may seem lacking, her +15% Stamina Growth should still help her get the stamina she needs.
Not only do these cards help Grass Wonder (Healer) level her needed Stats (especially with Rainbow/Friendship Training), but they also provide some needed skills like Swinging Maestro and It's On!
| Alternate Cards | ||
|---|---|---|
Mayano Top Gun (Cute + Cute = ?) Rarity: SR Type: Stamina Great general-purpose Stamina card |
Manhattan Cafe (My Solo Drawn to Raindrop Drums) Rarity: SR Type: Stamina Long skills and decent green skills |
Marvelous Sunday (A Marvelous ☆ Plan) Rarity: SR Type: Wit General-purpose speed skills and debuffs |
Agnes Tachyon (Experimental Studies on Subject A) Rarity: SR Type: Wit Great Medium speed skills and debuffs |
||
If you do not have the cards from the recommended deck, you can replace them with a similar stat card that provides skills that Grass Wonder (Healer) needs. These can be SSR cards or even SR cards. Above are some of the SR cards that you can use in place of SSR Support cards.
| Recommended | |
|---|---|
| 9★ Speed 9★ Power |
|
| 3★ Late Surger 3★ Medium |
For Legacy Sparks, we recommend trying to find Speed and Power sparks to help with Grass Wonder (Healer)'s races. For race length Sparks, Medium Sparks are a must as she has three Medium career races while only having a B aptitude in the race length.
For running style, get Late Surger sparks as you will mainly be running her as a Late Surger.
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.
| Great | |
|---|---|
| Good |
When picking Legacies, try to select compatible legacies, as they increase the chance of inheriting additional sparks during the Inheritance events. This is not required, but is highly recommended.
If you do not have access to fully compatible legacies, it is enough to ensure that you have at least good compatibility with your selected legacies.
Grass Wonder (Healer) is a Late Surger, so having acceleration and speed skills are important when it's time to overtake other runners. Skills like It's On!, Outer Swell, and Professor of Curvature can help Grass Wonder pick up speed in different situations.
Homestretch Haste can provide speed during the final stretch, and can potentially synergize with Late Surger Straightaways. Fighter and Straightaway Acceleration are both acceleration skills that can potentially help you overtake opponents.
For recovery skills, Swinging Maestro and Relax can recover Grass Wonder (Healer)'s stamina at opportune times. During Long races, you can even get Cooldown to increase your overall stamina recovery.
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 (Healer) can activate said skills in a race.
