The Light In The Dark

When The Light In The Dark is put into a
graveyard from anywhere, shuffle it into your
library.
At the beginning of each combat, put a
+1/+1 counter on target permanent you control without a +1/+1 counter on it. Then, proliferate.
{2}: Target noncreature permanent becomes
an X/1 creature in addition to its other types
until end of turn.
