Answer 1

Look at your Marking Map on your Poketch. It's the same as how you find the Legendary Dogs in Pokemon FireRed/LeafGreen.

You also find Cresselia this way once you visit Fullmoon Island.

Answer 2

first look at your map and you should be able to see where its located, and I think its those moving little bubbles, oh and btw you should have something like a wobbufet cause mesprit always runs away, but if you use wobbufet his ability prevents escape or instead have a pokemon that knows mean look and is fast

Answer 3

go to the poketech developing appartment and update your poketech then you can see it in your poketech and you need a masterball or a lv 50 wubbafet to catch it

Answer 4

Is a bit hard to catch Mesprit cuz whenever you change a location as this Jubilife city  to Road 211 the Pokemon will go to another place.

What i do is to see where are the places were he hides and i change the road until is in the road i want

You have to find the way its better for you.

Hope I Helped (;

Answer 5

go to the poketech company to get it

Answer 6

talk to the prof. and he will give a poketech app. and then the poketech will show where it is but it will move if you fly so use a pokemon like wobbuffet cause of its abitliy shadow tag.
