WARNING!!!!!!!!!!!! DO NOT FLY OR USE YOUR BIKE UNLESS INSTRUCTED DIRECTLY TO!!!!!!!!!
Go to solecean town, or if you don't have fly yet for some strange reason, simply ride your bike there. Now, on your watch, go to the marking map app. Simply ride back and forth from the route underneath the town, to the town.
The best and fastest way to capture the Pokemon is to simply stand at the place where solecean town turns into route whatever.
Now, when the Pokemon goes underneath hearthrome city or if it goes under socelean town, simply go to it. How ever, if you are in socelean town, you won't be able to as it might move to far away.
To catch one of the Pokemon that appear on your marking map ( Mersprite or Cresselia ) when you are in the same place as the Pokemon, use the circle mark. I don't know if any of the other marks will work. However, use the circle mark for the first couple of times. Place the mark on the Pokemon then go into some place that Pokemon normally appear. Now either run or walk to the Pokemon ( I suggest you run )
There are three Pokemon that you can get using this method. You could get Mersprite ( the battle music will change as all you hear at first is nothing), Cresselia ( the battle music will stay the same, you will just have to wait and see ) or whatever Pokemon that is in this area.
BUT WAIT!!!! WHAT'S THIS?!?!?! When you attack the Pokemon, it will flee. Don't worry. The next time you see it, it's health will be down to how it was when you last encountered it. I have heard rumors that you should use a nest ball. It captures Pokemon that are weaker than the Pokemon that you are using. I don't know if that works. However, I do know that a ultra ball seems to have no affect on it just a garintina.
I have lowerd Garintina and Mersprites' health all the way down to one before. However, a master ball doesn't seem to work on them. For Garintina, it simply wiggles twice and then comes back out to say hello. For Mersprite, it seems to laugh at you and in one or no wiggles will pop back out.
I hope I have helped you. To catch Garintina, type in the search bar Where is turn back cave in Pokemon diamond shadowthiefdark answer. Happy huntings!

First of all, you catch Mespirit with the marking map not Alzef. And second, Cressila is the other Pokemon you catch with the marking map.
Use the marking map to track her down.
use your pokeapp
only Pokemon that run away will be shown on the marking map
Zapdos, moltres, and articuno are only roaming around in Platinum.
put the maeks on the Pokemon and it will stay in that spot don't fly to it u have to walk or run and good luck!!! In the search bar, put in how do you use the marking map in Pokemon diamond shadowthiefdark answer. Be sure to check my other answers, although I didn't answer this one. Shadowthiefdark

On the marking map you can't mark Pokemon but if a Pokemon is roaming it will be represented by a Pokemon face.
in Solaceon Town, but to get marking map go to jubilife and to the app station
Use the marking map to track her down.
The marking map app can be found in Jubilife city from the Pokétch company. Talk to the owner and he will eventually give it to you.
use the diamond etc from down the bottom and just6 drag it to where you want it.
the poketch marking map can be obtained by the poketch president after getting the 5th or 7th badge
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
If you have the marking map it will track mesprit, just don't fly.
