Yeah, I used Call of the Winds frequently as Helheim. Put the birds on Guard Commander on a mage, or on a commander set to Hold/Hold/Hold/Hold/Hold/Stay behind troops. Problem is that if an attempt is made to break the siege on the same turn you summon the birds, they don't have orders yet and so they charge into combat. Later on I prefer Gate Cleavers and Wall Shakers, but the birds are pretty okay at breaking sieges and give you flying commanders (who are *not* upkeep-free) to shuttle troops around.
