Wow, this is going to come up a lot later than I thought, but life sure gets in the way some times!
Let's talk about Mivindal. I personally like him. He pretty much gives you an extra copy of any mandiblor in your army. On top of getting an extra fighter for free, you get an additional mugic counter to cast one of your mugics if you need it.
Mivindal is the creature version of Talisman of Mandiblor, but you don't have to wait for him to be engaged so you can use his ability. This makes him more versitile than a regular danian mugic caster with a Talisman of Mandiblor, but choosing between the two of them is a matter of preference.
