Angel's Undeath

Angel's Undeath can't be countered.
You can't lose the game this turn and your
opponents can't win the game this turn. Until
end of turn, damage that would reduce your
life total to less than X reduces it to X instead
where X is your devotion to white plus one.
"As divine flesh became ash at the great demon's
hands, a yet truer form emerged from the spirit set
free."
