Kithkin Seeker

When Kithkin Seeker enters the battlefield, you
may have each opponent gain three life. If you
do, search your library for two basic lands,
reveal them, then put one onto the battlefield
tapped and the other into your hand. Shuffle.

{1}{w}: Kithkin Seeker loses all subtypes and
abilities and becomes a 1/1 Bird with flying
until end of turn.
