I am a bit confused about exhausted units.
Lets say Player A uses card 1 attacks card 2. Card 1 is exhausted. Can Player B uses card 2 then attack card 1?
Lets say Player A uses card 1 attacks Player B's card 2 and destroys it. and Card 1 is exhausted. If Player B already had Card 3 dedicated to the fight, can Player B uses Card 3 to attack Card 1?
