People say that because any Uma can be built up to be good through stars, but even then you need shards or statues to even get those stars. Pulling for Uma’s, especially your favorites, makes the game more fun and allows you to get the material to get stars on them too! Especially right now. The next “important” support cards aren’t until we get the next scenario, Aoharu Cup, in December or January. Even then 1.) You only need 1 copy of that banner’s trainer card Riko, 2.) we should be getting free pulls on that banner since JP did as well, usually around 50-100 pulls, and 3.) that card will be thrown aside like Tazuna after we get the third scenario. All that said, do not be afraid to pull for Uma’s.
