Mesprit and Cresselia, VERY easy. - Pokemon Pearl
Print this Mesprit and Cresselia, VERY easy.
Say you used your master ball on plakia/dialga/uxie/azelf/etc.
Cant get mesprit or cresselia? WELL I know how. Once rowan tells you to check with the president of poketech, talk to him (may have to be more than once because of other things) till you get the map thingy, find it on you poketech, see that monster face thing? Good... Now, head south of jubilife city, once in the top right it says youve reached route whatever it is, keep going up and down, example
Keep going up and down somewhat slow till it pops up in your area. This is best place since, A) weak people B) no caves/forests to cause problems
Now, when mesprit/cresselia is in you area. SAVE incase you kill it (unless you want to kill it, be my guest and do so, remember, only one of them) weaken it till it's in red, you may have to repeat the step till it gets in your area. Now get someone like a roselia that knows grasswhistle or someone with sleeping powder. It can still run when asleep but sleeping it rises the chances, and since it's in red, and asleep you'll most likely see it first time when it's in your area
Now the easiest part, get about 10 quick balls (just incase, and if you want 20 or 30 incase you want to catch level 50 people [on island after E4 and national] cause thats what I use to catch those people) whenever you encouter mesprit/cresselia use a quick ball and pray. After a while you WILL get it (or if you want to, use dusk balls if it's night, I didnt do that, but you could try)
Good luck and enjoy those legendaries (all I need of the non-event people is
