I have soulsilver, but I caught Ho-oh so its basically the same thing. I waited until night time, and then used a dusk ball. Seeing lugia is in a cave, I would use a dusk ball. Lugia is also very heavy so bring lots of heavy balls.
Hope this helps!
with a poke ball
get a poke ball and catch it Problem salved
you have a special poke ball ( NOT ON THE GAME) which you can buy in toys R us and then connect it to your game then you can put Pokemon into you poke ball from your game and then you it will count how many steps you do and should make you Pokemon in the poke ball fitter (Hope this helps)
No, this is only possible in Pokemon Yellow and HeartGold/SoulSilver.
The only way to get a Premier Ball in HeartGold or SoulSilver Versions is to trade a Pokemon holding one or by buying 10 or more Poke Balls at a PokeMart.
Search for wild Pokemon in different places and when they have low health, capture them with a poke ball.
Yes you can get the Poke Radar
weaken lugia down till it is almost dead than use a poke ball you will not catch it but then use an ultra ball and then you have lugia. PS. use the master ball on entei
