Shade God Leander

Flying, Lifelink, Deathtouch
When Shade God Leander enters the battlefield
you may search your library for a Legendary
Creature with converted mana cost of 4 or less
and reveal that card then add that card to your
hand and shuffle your library. If you do not
control a Shadow Token and another Shade
creature you can sacrifice this card and if you do
exile all permanents your opponent controls
except non-basic lands. During each upkeep
phase pay {b}{b} or sacrifice this card.
