I think that soldiers should be more focused on armor, i mean, It is supposed that they use more armor than the nr. Maybe adding some armor to present units and more soldiers that synergize better with armor. I'm thinking in an archetype that it's main goal is to bring units that are protected, with abilities such as: "give all your bronze soldiers in your deck, hand and board 1 armor", "deal the same damage to a unit that the armor this unit has", "while this unit has armour, do 1 random damage to a enemy unit", "every turn gives 1 armor to a unit in your hand", etc.
