I would wish to see game turn offer day and night turn. Units attribute and bonus may adjust during turns.
eg
a) On day turn, ghost will reduce speed movement point from 20 to 10. While regain speed movement point of 20 back at night.
b) On day turn, crusader may add + 5 attack. Lost the +5 attack at night turn.
c) On day turn, demon lost flyer . Regain flyer at night turn.
