Herald Of Vitality

Whenever you gain 5 or more life reveal the
top three cards of your library, you may put
all cards called Leyline Of Vitality into the battlefield, otherwise play two lands from the
cards among them.
As long as you control Leyline Of Vitality,
creatures you control gain +0/+1, and shroud. Creatures you control assign damage equal to
their toughness.
