Pokemon Black: How to Catch Archen
Archen is a new rock/flying pokemon in Pokemon Black and White. Archen evolves into Archeops at level 37.
Archen can not be encountered in the wild. The only way to receive Archen is to choose the correct fossil in Relic Castle. If you choose the Plume Fossil, you can bring it to Nacrene Museum and have someone there revive it into Archen for you.
