I think it would be very helpful, when playing against another person/npc, if when you knock out their beast and they are about to bring in their next if you were allowed to change beasts without the one move penalty that results in automatic damage. That way if you know they are bringing in a Flame type you don't have to be stuck with you Flame type out you can bring in a Water type. Also, announcing what type is about to be brought in would be helpful.
