He who Hungers for the Stars

He longs to enjoy the randomness that is thrust upon
the sky at night, but is only able to handle mere snippets
of it.
When He who Hungers for the Stars enters the battlefield,
return He who Hungers for the Stars to your hand.
As an additional cost to cast He who Hungers for
the Stars, sacrifice He who Hungers for the Stars.
