I found the legendary bird trio in crown tundra, and zapdos flew to the wild area. I chased it down, and tried to Catch it. Unfortunately, my Pokemon were level 100 and it was level 70, so it was hard to catch since my Pokemon are already stronger and I KO'd it. A sign came up saying zapdos flew to somewhere else. Later, my game autosaved, so I couldn't retry! Where can you find zapdos if you defeat it before? If so, are there any good strategies to Catch it? What's the best pokeball apart from masterball to use? Can these strategies be used with any other legendaries in crown tundra?
