Shadow, Shroud
Whenever a creature die ArashiKun, the fallen
lich gains +1/+0 until end of the turn
While ArashiKun, the fallen lich have 4 or more
power, it loses shadow and gains indestructible
Whenever ArashiKun, the fallen lich deals 4
or more damage to a planeswalker, transform it
to restore my powers, I will break the watch
