What about Pal cards?

Pal cards are often short lived but very powerful in their respective scenarios. However, you need a strong deck to support them right now, as they give little stats on their own. Aoi can be used when making parents, as she gives lots of skill points to buy more skills for more white sparks. Tazuna is strong for her Concentration skill, which can be used by any uma in Team Trials for easy points. Once your cards are at MLB, try slipping in a pal card and see how it goes.

In the next scenario, Aoharu, there will be a pal card called Riko that is extremely strong in Aoharu. You will even use her Rare version in your builds if you don’t have her SSR. She’s probably the longest lived Pal card, remaining useful in scenario 3 for longer distances, and technically usable in the fourth scenario but falls off in favour of Light Hello, who then falls off and is replaced by the Goddesses, and so on.
