Mechanized Production
 
Alternate win conditions are always going to get attention, and rightly so, especially when they change the way a deck approaches a match. This card is probably about as close as you're going to get to an "economic victory" style in Magic, and is an interesting twist for decks based on copying and cloning things. It works equally well when you're copying someone else's things and your own things, and even when you are just going all-in on Sharding Sphinx. I expect this card to get a lot of attention in casual and EDH settings, so be ready!

Mechanized Production (2/20)
 
An instant-win card always will get noticed. Mechanized Production is most notable for that little bit of text (“you win the game” always gets attention), but it’s better than a card like Barren Glory in that it gives you something even on turns you don’t win the game. The win condition doesn't need to be 8 copies of the enchanted artifact, too; it could be, say, 8 Servo tokens or 8 Thopters. Ideally Thopters, because Thopters are legit.
 
It's a four mana enchantment that doesn't start working until the turn after it resolves, which is a problem. It’s an Aura, which also is a problem (Auras are very fragile). If you can protect this, it can  legitimately win you games. But protecting it can be a problem, and you need a good shell to get this to do more than maybe make one copy of an artifact during the game.
