Today, I decided to go catch Terrakion. I flew over to Humilau City and quickly healed my team at the Pokemon Center before walking over to Route 22. I soon found Terrakion's spot, saved, and then battled it. My Krookodile went up against it, but killed it after I accidentally clicked on Earthquake. >_>
I soft reset my game and tried again, this time getting Terrakion's HP pretty low using Krookodile's Crunch. Then, I switched to my Rotom and paralyzed it with Thunder Wave. After that, I was ready to start trying to catch it. It took a little longer to catch than Cobalion and Virizion did, but it still only took about 22 Ultra Balls or so.
