You have Specters Mausoleum as a ranged tower, but the KRV trailer shows that it's a magic tower.
There are 5 towers that appear to be "obviously" magic towers, the mausoleum, infernal mage, orc shaman, cultist gem tower, and witch hut. I suspect the witch hut is the odd man out -- screenshots seem to show that the witch hut puts a flying witch unit in the path.
In case someone is curious but hasn't gone to look at the teaser site:
