Which Dragon did you pick?

Not sure why you're so keen on Paladin Phantoms? I have Paladins in my army but I also have Royal Griffons and those seem the best bet for the Phantom spell. Grab the Summon skill on the magic tree and it enhances their ability to call in their Divine Guard or whatever those ghosty griffons they call in are called.

Using Phantom on the Royal Griffons essentially gives you twice the phantoms and all of them ALWAYS counterattack. I send the original Royal Griffon stack just outside of melee range, phantom them, use the Divine Guard from the original stack, use the divine guard of the phantom stack and I've got 3 flying meat shields you can put anywhere and always counterattack. Phantom on the Paladins seems inferior on a lot of levels, especially in a no-loss or minimal loss game. Inquisitors would be your secondary rezzers anyway.
