Nu, Master of the Aix

Whenever a nonland-permanent enters the battlefield
under your control you may exile a card
from any graveyard. If you do then target creature
you control gets a +1/+1 counter.

{1}{r}{r}{t}: Exile Nu, Master of the Aix then you
may put any exiled permanent onto the battlefield
under your control without paying its mana cost.

Even beyond the reach of the Necromancers, I can
still reach you.
