Shadowverse

In the anime, there's also Dashka.

And why are only legendary cards made of deer, monsters, and fortresses, while the best content is just some insignificant silver card?

But what difference does it make? The color of the frame doesn't make one card better than another. For example, any girl from the Artifact deck >>> Dew. Judging by the color of the frame is being a narrow-minded person. I also like the deer. It shoots lasers in a cool way.
