Yesterday, I caught two legendaries. I caught Cobalon with relative ease, I weakened him with Kojofu, then lowered his accuracy with Waruvial's sand attack. Then, I used false swipe a few times with my Onondo and caught Cobalon with a Dusk Ball.
I also caught Virizion, but it was a little harder to catch. I weakened it with Enbuoh, then I used basically the same method. First, Virizion kept healing itself with Mega Drain, but then I got lucky enough that Waruvial could survive long enough to lower Virizion's accuracy by a decent amount. Caught it with a Dusk Ball.
Today, I caught Voltolos. He was really hard to catch, since he kept fleeing. I weakened him with Onondo, but he was still hard to catch. So I went on Bulbapedia, and I found the Move Relearner. I went to her, and wasted my only Heart Scale on teaching my Zebruika Thunder Wave. I found Voltolos again, and I paralyzed him. It still took me another half hour before I finally caught him, though.
I'm also carrying around a Meraruba egg, waiting for it to hatch so I can add it to my Pokedex. It's still not even close to hatching for some reason.
