Yes not fast at all
with a poke ball no just kidding catch raikou with net ball entei ultra siucune ultra or level up your Pokemon to 40 depending on what type it is and try to use scary face and use quick ball the first time u meet it and prey
gatch them with a master ball but trade the master balls
beat the elite four. This is true. But, you have a greater chance of finding one of the legendary dogs on Route 1. Use your master ball for it. it can run away. (don't worry-you can catch mewtwo with an ultra ball- I've done it.)
you can capture the legendary ho-oh when you've already catch the three legendary dogs. go to the tin tower, talk to the man inside for Rainbow Wing and suddenly, a stair appear. go trough it, solve some puzzles, and finally, the legendary ho-oh will appear. It leveled 60 and uses Gust, Recover, Sunny day, and Fire Blast. DON'T USE the master ball (if you have one), because its little bit easy to catch(I just need 3 Ultra ball to catch it, maybe its my luck), but stock a lot of Ultra Ball. Happy catching!!
the easiest way to catch suicune is to have 15 or 20 max repels the go to cerulean cave. surf around in the water until you find him. you will want to use all of your ultra balls then it will boost your chances of catching him by using a great ball.
You can catch any pokemon with any ball, you just have to be lucky. I recently caught a Zapdos with a regular Pokeball.Fastballs are a good ball to use at the start so they're probably your best chance at catching the legendary dogs without a pokemon with Mean Look/Arena Trap/etc.
no
no.
None of the legendary dogs are available in Emerald you must obtain them from Firered, Leafgreen, or Pokemon Colosseum.
i dont think you can, you can get the dogs only by action replay
Ho-oh lugia celebi(with a gameshark)
yes if you can find them
