Power prices won't be affected by unlimited proxies.  There will always be a demand for power as long as people are still playing type 1.  A lot of people would rather play with the real thing, instead of scribbled up lands.  Reprinting power, even if for proxy purposes only, by WotC could lower the prices.  I have the collector's edition power, and thus don't feel the need to buy "the real thing" because it feels like a real magic card.  Doesn't mean I wouldn't like to win them though....


This is a way to control how many scribbled cards you would have to face in a tournament, allow the tournament organizer make more money (to make up for any potential decline in sales), and will draw more people to the tournaments.  Also, people who already invested in power will reduce their cost of entry fees and increase their prize / entry fee ratio.

If there is a fast way for Oath to win a mirror match, then yes it'll become the next Goblin Welder (or, in a sense, Mishra's Workshop).  But if the Oath vs Oath matches keep going to time in the swiss rounds it'll hate itself out.  It'll be interesting to see what shows up at SCG III.

I think the reason why both Copy Artifact and Sculpting Steel aren't played much is that they're conditional on another good artifact is in play already, and there are better answers available for the cards you would want to use them on.

One example listed was a fish deck copying Darksteel Colossus.  Sounds great, but the problem is your opponent still has the Darksteel on his side of the board.  But Fish has Sigil of Sleep, which for one blue mana you can put on a flyer or a mancer and just return it to his hand (or any other creature he plops down).  Using it as a creature stall just doesn't seem productive to me.

So that means using it to duplicate non-creature artifacts.  Well, you wouldn't use it to duplicate Moxes (that just gives your opponent a free time walk that YOU paid for).  You could use it to duplicate gilded lotus, giving you lotus 6 through 9, but what deck needs that kind of mana?  Duplicating things like your own creatures seems like a win-more situation to me as well.

The only thing I can picture using Sculpting Steel for, would be for a welder deck.  Have it in your graveyard, and weld it in when your opponent plays his legendary artifact (causing both artifacts to be buried under the new legends rule).  Again, that seems too narrow, and there are better ways to remove his legendary artifact.
