i caught lugia with the ball-that-works-better-in-dark-places by putting it to sleep after knocking its hp down, and then throwing it. caught on first attempt. I was ecstatic.Three attempts later and I caught it with the second Ultra Ball I threw, and it wasn't even paralyzed ._.
since then lugia has surpassed my typhlosion (which is neat, 'cause my typhlosion had the poke-disease thing, so it has maxed EVs), and is now the most powerful member of my team.
my team is lugia/typhlosion/latios(the blue one)/scyther/haunter/something-else. screw the taboos against legendaries, if i get them i will use them (if they look good. i am superficial when it comes to my pokemon). it helps that i don't care to play online.
