Alolan Vulpix and Ninetales
Even stranger than an ice/steel Sandshrew is Alola's frozen take on a classic fire pokemon. While not really my personal cup of tea, everything I had to say about fire Vulpix still stands - it's a cute, organic design with nice non-anime eyes that it gets to keep through its evolution.
I will say that ice Ninetales is actually a bit cooler looking, to me, than fire Ninetales. Its wavy, whispy fur gives it even more of a ghostly youkai vibe, evoking a cloud of evaporating mist.
Not particularly innovative, but not too expected, either.
