Thenaar, the Pale Stream

Flying, soul-link (whenever this creature is
dealt damage you gain that much life.)
{1}{g}{g}: Exlie target creature card from your graveyard. For as long as that card remains exiled
you may cast it.
She began as a seed, for centuries she was bound by
root and stone. Now she sows the seeds of life as the
ever flowing mana stream pours from her breast.
