I was in a wifi triple battle. My opponent had Sylveon, Greninja, and Aegislash in that order. I had Greninja, Crobat, and Ferrothorn in that order. It was the first turn, so my Crobat was under no status condition or stuffz like that. I selected to use U-turn on Greninja with my Crobat, and my Crobat moved first as all the other Pokemon were slower; but it missed! How did it do that?
