You just remembered me I've started to write a guide some weeks ago and should finish it and post (perhaps tonight if I find time).

The fact is there are a lot of good possible build and strategies for Arco, not just one or two very obvious choices like for many nations (so trying to list them, I never finished my text).

Anyway, you may find many good strategy posts for Arco in old dominions 2 threads, ME Arco is essentially the dom2 nation.

The guide for communions is something to read too, very usefull for Arco like for all astral nations (the reverse communion thing can be seen as a new strength of the nation, making mystics very interesting mages).
