I don't know how often you have him out, but you can have some fun with mono-artifacts using Glacian's tap ability. Blinkmoth Nexus and Winter Orb will only work when untapped, so you can tap Orb on your turn to break parity and tap Nexus on your opponents' if you don't want to give them the mana.

You might also like Unwinding Clock , and I'm very surprised to not see Duplicant !

Definitely trying to stay away from Winter Orb and the like. That kind of playstyle isn't really my thing. Blinkmoth Nexus seems interesting, though.

I think I just ordered an Unwinding Clock in my last batch of cards from TCGPlayer.

Duplicant is one of those cards that must've slipped through the cracks when I was doing research and is an easy include. Replacing cards is getting tough, though. Suggestions?

Oops, I totally spaced and meant Blinkmoth Urn which makes way more sense!

My first cuts for Duplicant and Urn if you want it would probably be Lux Cannon and Scourglass , because your opponents have a lot of time to respond or deal with them; if you want to keep one of them, maybe Dramatic Reversal .

Dramatic Reversal is kind of weak as it would really only be used to double up on Glacian's activated ability once. Come to think of it, maybe replacing that with something like Rings of Brighthearth or Lithoform Engine would be a better replacement for that?

Lux Cannon and Scourglass are some of the deck's only means of removal, so I'd like to try and keep them in. They're not in any sort of danger from removal most of the time, though, because once Rebbec is out, both will more than likely be immune to targeted removal.
