U NEED POKETCH APP MESPRIT IS STILL IN CAVE YEYZ
Its not Azelf its Mesprit that flees and you get it by using the Pokemon tracker app and you wil need a Pokemon with mean look so Mesprit does not flee.
there is nothing you really need to do with azelf, uxie, and mersprit. you just need to see them to complete your pokedex.
you need azelf,uxie,mesprit to open the cave after beating the Pokemon league
you need the marking map on your poketech and the you go between sangem town and route 219 until he will be down in the marking map and then go into the sea there
Talk to Mesprit. It will run away and professor Rowan will come talk to you and say you need to the Marking Map on your Poketech. You can get this from the President of the Company after your 3rd badge. Anyway, look at the Map you should see a strange flashing symbol- that is where mesprit is. Chase 'em - When you are were the symbol is run in the nearest grass/water/cave ground til you find 'em or it moves off. You can use status problems, but even asleep mesprit will run away. Weaken 'em and through balls and KEEP CHASING! :)
You can find Mesprit in Verity Cavern. Head to Lake Verity and use surf till you find a cave. Inside will be Mesprit. However, it will run away so you will need the Marking Map app to find it.
to get azelf if you've fainted it or ran away you need to beat the Pokemon league
You find them all at separate lakes. You can catch Uxie and Azelf at their lakes. Mesprit flees again when you go to her lake. You need to use the map marker poketch app to find it. PS: Don't fly towards the Mesprit. It will go to a different spot then. Use your bike or run to get to it.
Mesprit can be found in Lake Verity after encountering Dialga, but as soon as you interact with it, it'll show its Pokedex picture, then teleports away. Mesprit can now be tracked down using the Map Poketech App. You can see that Mesprit travels around Sinnoh and may teleport away when you reach its current location. (This is known as a Roaming Pokemon like Raikou, Entei, and Suicune in the Generation II games.) When you reach its current location and it haven't move, you will need to walk in the Tall Grass or surf on the water to find it. However, if your Pokemon is slower, Mesprit will flee before you can use a move.
After you caught or battled Palkia go to Lake Verity and once you encounter it it'll flee. You need the Map Poketech App and look for where it is. You also need Pokemon with the Shadow Tag or Arena Trap ability or they have the move Hypnosis, or Mean Look. Make sure the Pokemon is faster than Mesprit.

You need the marking map you used to catch mesprit You need the marking map you used to catch mesprit
you need to go to canalave city and talk to professor rowan and he'll sent you on a mission to get them
To catch Mesprit you need to surf to the middle of lake Verity. There you will find a cavern in which Mesprit lives. After you talk to it, it flys away! When that happens, Professor Rowan talks to you. After he leaves, get out of the cavern and start chasing Mesprit! To chase Mesprit, use your poketch app Marker Map to find Mesprit's icon(it blinks!). Instead of flying to the nearest city, which makes it run away, walk or bike all the way to its icon and look around in the nearest patch of tall grass. it often runs away, so be careful!
