Have couple cards I notice bot just wont play, its just hold( holding is bad because instead of holding this card I could hold card I could play)
Darnassus Aspirant - this card bot wont play until it ran out of card to play
Wild Growth - wont play this card to up maximum crystal for next turn + future turn. even with left over crystal when turn is done. but it will play when crystal is max at 10... I could hold other card I could be playin all this time.
