The Dreamwalker

Double strike, protection from Nightmares
When The Dreamwalker becomes the target of a
spell or ability, exile it, then return it to the
battlefield under its owner's control.
When The Dreamwalker dies, put it into exile
instead of its owner's graveyard.
In every dream she strides and waits to find the
will to make those dreams real, and from her light
the nightmares flee.
