Living City 750pt
*Battle Regiment* - Vendetta Grand Strategy
Runelord (Genera)
Arcane Tome, Master of Magic, Curse, Lifebloom
10 Irondrakes (Honoured Retinue)
Torpedo, Banner, Hornblower
10 Irondrakes
Torpedo, Banner, Hornblower
Drycha Hamadreth (Coalition)
Ironoak Skin
From what I can understand this is legal?
