Also, i would like to suggest one skill: delay. This should be skill of very powerfull cards since it offers benefit of prolonging time of enemy deployement randomly. When this card is activated, it slows down randomly deployment of assault enemy cards by preventing ticking. Some very irritating decks could be developed in this way.
If this wasn't mentioned beffore, i would like to suggest one awesome action card: sacrifice. It kills randomly one of your assault cards by boosting attack of rest of played assault cards by 1 and in addition heals them as well by 1. this could well used with deck filled with low attack/fast cards in order to provide instant damage boost and protection.
