Phyrexian Portal would be nice... My collection is lacking.
Icy Manipulator. Can you imagine if this thing was printed in MM Block? It would certainly be a power card, but not too broken, as it's not really a Port due to the high casting cost... And no, Ring of Gix is NOT a replacement for Icy. I want the real thing!
How about a reprint of everyone's favorite annoying artifact: Static Orb.
Gee guys the only artifact worth reprint has to be bottle of suleiman, such ramdomness and chance are the way that magic should be! no deck should ever be unkillable, and every deck should be able to take its own life too!
