Yes. The only Physical Move I'd ever run on a Whimsicott is U-Turn (if you play on Set Mode) to get the advantage over your opponent. All of Whimsicott's Support Moves get Priority so moves such as Encore, Taunt, Charm, and Tailwind work really well for certain situations. A Fire Move is good to have alongside STABS so Whimsicott could stand a chance versus Steel Types.
