Even with all its limitations (only Rohan, costs a Restricted slot unless you are Theoden, unique) Snowmane it's a really good action advantage card and can go on a few good targets, like Éowyn and both versions of Theoden. It can also be fetched by the in-sphere Westfold Horse-breeder. In my play experiences we end up playing it on Théodred since it's the only Rohan hero we have and being able to use his 2 is nice.
