Hey so I would recommend Theia in Heroic for the extra population with dryads. Also Stymphalian Birds are great for raids, especially in teamgames and verse norse. In mythic I almost always go Hekate for the tartarian gate which you want to use on the enemy back tc usually and away from the location you are pressuring. You do this to pressure them and overwhelm them with essentially two different attacks at once and they will most likely not know how to respong properly.
