Shadowverse

Update: The Snow Queen has round ears, so what I wrote is nonsense; she won't be associated with any forest. Update 2: In the comments on Reddit, they suggest that this is Snow White. I don't know. I perceive this as a proper name and don't associate it with snow, but rather with dwarves and apples. Update 3: In the comments on Reddit, they are also predicting that it's Barmaglot. Update 4: They posted art from the Rob Wiki; it turns out it's Snow White. Update 5: The dragon is indeed Barmaglot. Gee, maybe I should have read the comments first and then edited this post every two minutes?!

"cannot be the target of spells or hero abilities" - they were probably just too lazy to write it out.

They don't shorten it in Heroes of Might and Magic either. But they indicate it with diamonds.
