Catching the right Regirock nature
I'm trying to catch the exact nature I want of Regirock and I just can't seem to get it! My first in line is Abra with the Synchronize ability and a the nature I want. The Abra is only lvl 10 and I send it out first, just to take the first hit. I've actually caught Regirock several times, so I don't need help in that strategy, but, geez, after close to catching him 10 times, I have still yet to get the nature I want WITH a synchronizer? Am I doing something wrong here?
