Magister Astalor Bloodsworn

under your control, you may pay {1}. If you do,
draw a card.
"Kael'thas and his felbloods be damned! All we've
worked for is gone, but they're fools to think we
won't fight back. Already, Lady Liadrin seeks a new source of power for our order. We will not be destroyed
so easily."
