You could try something with orcs such as:
Orc
Ogryn
Cyclops
Gar’nok
You’ll have the same 50% of mana on all troops (Gar’nok), Ogryn gives 5 to all stats on your team and you get at least some board-modification/mana generation with Orc’s spell to use when you are able to gain an extra turn while filling Cyclop’s mana to remove Lady Ironbeard armor. And if you are lucky enough maybe some skull cascades will make your Orc hit Lord Ironbeard for a 40+ damage (Enraged) ignoring traits.
