MTG Salvation

Or, instead of theorizing why it might not be as good as people say, you could just test it and be sure.

Then, if you're still underwhelmed, you get to know for sure that you were right. And what's better than that.

When it costs a "Grant" to obtain the card (I don't run proxies) then I'll stick to theorycrafting. I have done similar theorycrafting with Serra, but I pulled one so I can and will try it myself. Also, its only been a few days since it has been available, so there really isn't a problem with theorycrafting at this point. If, a few months later, others experience continues to support this card then this would obviously carry more weight than what I'm saying now.
Regardless, I know how my cube plays well enough to know how it would likely perform in my cube and similarly constructed cubes.

Urza is like a $36 card now. Expensive, but not unobtainably so.

Regardless, you don't need an artifact deck for him to be good. Just some artifacts in your deck. There's a big difference. Cubes with artifacts in them should be able to make Urza pretty busted with minimal effort. It isn't nearly as deck-specific as a card like Tolarian Academy or Tezzeret, Agent of Bolas.

Urza isn't JTMS good, but it's still a spectacular cube card that's both powerful and fun. I would proxy one up just for testing in the next few drafts, and see if it's worth ordering one. You don't need to "run proxies" in order to do good playtesting.

So kind of a funny story. I joined a friend to play sealed MHZ with his box today and I cracked 6 packs. Among the cracks I packed there was a foil Nurturing Peatland and a Sword of Sinew and Steel and on the 6th pack I shotcalled an Urza and then I pulled it. Wish we would have videotaped it.
