Frankly, then they just super-speed kill your protector. Due to the insane boost from scarves for speed you'd be a fool not to use them except on a mega as speed seems to be a major factor this meta, so its always mega diancie/aggron who has it then they die from talonflame, lopuny or bisharp. As I said, I have had extreme speed fail against scarfed fakeout so I'm not even sure protect would be enough.Actually, protect is a completely viable strat. Fake out only works on the first turn out, so protect gets rid of that threat. After protect, you can threaten with a priority move or just attack if you're faster.
