Well, it has the Catch Rate of 5. So it's pretty hard.
There is no easy capture just luck but for the beginning its easy to catch some pokemon.
You catch them at Mt. Pyre! Also you can catch Groudon and Kyoge very easily. Just weaken their hp to red and throw 6 ultra balls! How easy! BUT save before you battle just in case you wipe them out!
you get it at the battle park for 32 b.p its easy to catch enti, rioku, and latios with it
a great way to catch groundon is to use like to ultra ball and use 1 or 2 premier ball and bring a water pokemon. groundon will be at level 45 when u battle him or capture him hope i help u
Easy , it's Palkia & Dialga
easy stroomish

EASY!!!!!!!!!!!!!!!!!!!!!!! you catch near the start of the game.
easy catch a mareep
Get the master ball
no
The master ball is the obvious answer, but you only get one in the whole game. It will always catch any Pokemon. Just stock up on ultra balls and save often, if you don't catch what you want you can just restart. Using a Pokemon with high HP and knowledge of sleep, paralyze or poison is also helpful.
