Whenever a creature you control is a target of
spell or ability, reveal the top card of your
library. Whenever you revealed a land, put it into
your hand, otherwise shuffle your library. If an
instant or sorcery is revealed from your Library,
create two 1/1 blue birds with flying.
Whenever you gain life, reveal the top card of
your library.
