Cressila is a roaming pokémon, which will roam the Sinnoh region, after you've encountered it for the first time. You can find it at Full Moon island for the first time. You need to be the Champion first and you need the National Pokédex, before you can visit this island.
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.

There is no TM for it. You have to catch a golbat that knows it. I can see your looking for Mesprit or Cressila. Train the golbat to 100 speed or your mean look will perform after it flees lol. ~Wariolink~ Pokemaster
