Lady of the Serene Sun

When Lady of the Serene Sun enters the battlefield, put a blessing counter on Lady of the Serene Sun.
For each blessing counter that this creature gets,
white creatures you control get +10/+10 and you
gain 10 life. When this creature is removed from
play, prevent the next X damage that would be
dealt to you and creatures you control, where X
is the number of blessing counters Lady of the
Serene Sun had.
