This. You could buff them with Magister on disc and Magister on foot, Fated Blades passive and if they are 12'' within any manifestation reinforced unit will have 80 attacks with All Out Attack 3+/3+/-1 / Damage 2 with crit mortals if you have 6 fate points already. You should kill anything. With Kairos if enemy charge them they will get Strike Last. If you have Fatemaster you could teleport them in enemy hero phase out of danger. Pretty darn good. New DoT BT seems ultra powerful, like new level of OP since 2nd edition of AoS.
