Strago Magus

When Strago enters the battlefield, Scry 3.
Whenever Strago takes damage from a creature,
exile that creature for as long as Strago remains
on the battlefield. You may use any ability of
a creature exiled this way.
If you control a Legendary Creature named
Relm Arrowny, Strago gets +1/+3 and has
Hexproof.
