Calset of the Hemlock Sodality

At the beginning of your upkeep, choose grey or
heart. If grey was chosen, put a random card you
own in exile into your hand and you lose 3 life. If
heart was chosen, you gain 3 life and exile up to
one creature card from a graveyard.
When Calset dies, if you don't control a Shade,
return it to the battlefield tapped and create a
0/2 black Shade creature token with "This
creature can't block or be sacrificed," then exile
the top card of your library face down.
