I'd like to suggest a new mechanic to the game, one that increases the point value of a card without increasing their toughness. There are many ways to apply this but the best would be to create aura type of effects. Currently the game doesn't have any and i remember it was awkwardly attempted back in beta with the Wild Hunt Drakkars.
You could call it morale or something and unit card can have effects like "Morale +2 while you control 5 or more elves" or can be buffers "Dominance: All units on this row have morale +1".
