A wolf and a penguin could never live together, nor could a camel and a hippopotamus. That would be absurd.
And the older you get, the fewer things you really love. And by the time you get to my age, maybe it's only one or two things. With me, I think it's one.
I attack with 2 cards in a column. I use a 5 CP commander as my bonus card and lose the battle.
Do I lose my 5 CP commander for the rest of the game or just the 2 unit cards?
The bonus card is just discarded. Only the card(s) in the column are given to your opponent.
