How To Get Latias And Latios Easier:

To catch Latias and Latios is easy. Note: Get lots of Max Repels and balls! First you need a Wobbufett or a pokemon that knows Mean Look. Note: Block isn't a move that's going to trap the two. Coz' if you use block, the Latias/Latios will fled faster. Get a Golbat in Sky Pillar that knows the move Mean Look. Surf in Route 124. You will find Latias/Latios there. If you chose Latias, i say it's easier to catch! Put wobbufett or a pokemon that knows mean look first in your party. Use a move that's not effective. Pokemon with the move False Swipe will make the foe's HP 1.
So i suggest False Swipe is good. Try freezing or making Latias asleep. Then, use false swipe. Then, use ultra balls.Note: When you're in the sea, use Net Balls. It will work better. To catch Latios, it's very hard. Try and use Wobbufett and Golbat again. Repeat the thing you did to Latias.
