Finishing Niv-Mizzet EDH

Looking to finish my Niv-Mizzet EDH Deck. Trading anything on my tradelist for the remaining cards!

Some notable haves are
-1x Jace AOT
-4x Sphinx's Rev
-2x Ral Zarek
-1x Hero's Downfall

Start up a trade if interested! I'm okay with trading multiple small things for something big!
