I think the bird of steel should be #6
Mostly because I think "legendary" pokemon are for noobs, but also because I think suicune could be more easily replaced when making a team.
Skarmory and Suicune are both great, they have both been in OU for 3 generations.
But in BW, suicune dropped to uu annnd skarmory didn't. So I think skarmory is better than suicune
Really I'm doing a tutorial on catching pokemon again? BITCH! I've been catching pokemon since before you were programmed!
