Nagash, Lord of Undeath

Whenever you cast a noncreature spell, draw a
card, then discard a card and put a +1/+1
counter on Nagash.
Whenever Nagash attacks, you may return up to
X target creature cards with total mana value less
than or equal to Nagash's power from your
graveyard to the battlefield, where X is the
number of noncreature spells you've cast this
turn.
