My other choice name was Climate Change, but much like moves, I don't think abilities have more than 12 spaces to them. I'd hope I were wrong.
I really don't like the name Ice Shell because the name sounds exclusive to Ice Types. I'm sure there are other Pokemon who would want easier switch ins who aren't ice.
MANY other pokes have near exclusive abilities that are done by a diffrent pokemon who has a different name for it (Vital Spirit/Insomnia)
