I've never used allies in 2.0 though I understand some of the stronger tournament lists sometimes had Stormcast hero allied in (this was before Malign Portents, I stepped out for awhile until 3.0 launched). But I have the Cities of Sigmar book (I'm really not particularly interested in Stormcast) and there's some fun stuff in there. I know people have been talking about the Battlemage of Ghur, who I've now come around to realizing DOES get that +1 to casts because it was never a Realms of Battle effect it's a Warscroll effect. Folks were also talking about the Frostheart Phoenix, but I don't remember why and don't see anything on its warscroll that really makes it seem any cooler or better than certain units or combinations of units from our own faction. It's pretty expensive at 220 points. It's been out of stock on the US webstore but I just got an email that it's now available for order. Trying to find out if it's worth the 220 points (and US $60!) or not. Who else is allying in units and what are they?
