So, I'm trying to catch Latias, and I got her down to yellow with my wobbufet's Mirror Coat, but no matter how many Ultra Balls I use, it's not working, and if I switch out of Wobbufet, she simply flees. Is there any sort of Item I can use, a priority move, perhaps, that I can use as an alternate way to stop her from fleeing? Also, I can't trade, so I can't get Crobat, unless there's another way to get a Crobat or Mean Look. Please help.
