Luminarch Ascension

At the beginning of each opponent's end step, if
you didn't lose life this turn, you may put a quest counter on Luminarch Ascension.
{1}{w}: Create a 4/4 white Angel creature token
with flying. Activate only if Luminarch Ascen-
sion has four or more quest counters on it.
Few other than angels have seen from where they
came. This is a well-kept secret.
