The Girdle of Melian

Untapped creatures you control have hexproof.
Creatures your opponents control can't attack
you as long as you control a legendary creature.
Threshold- At the beginning of your upkeep, draw
a card and gain 2 life if there are seven or more
cards in your graveyard.
"Melian put forth her power, and fenced all that
domain round about with an unseen wall of shadow"
