Zero mana artifacts are prevalent in the likes of Modern and Legacy, with Mox Opal, Lotus Petal, and Mishras Bauble all seeing heavy play
Note: Cards at a 7 or lower for centering may have a chance at the MC (Miscut) qualifier
(Tarmogoyf's reminder text in Future Sight did hint that the card type was coming.) The core of the Lorwyn design team (Aaron Forsythe, Paul Sottosanti, and myself) did the majority of the second half of planeswalker design
Lands (22) Spells (38) 2 Brainstorm 4 Counterspell 4 Force of Will 4 Accumulated Knowledge 1 Impulse 1 Capsize 3 Intuition 4 Merchant Scroll 4 Donate 4 Illusions of Grandeur 4 Sapphire Medallion 3 Fire Sideboard The combo of Donate + Illusions of Grandeur seemed over the top in those days, giving you a twenty life boost and saddling your opponent with a liability that would rapidly become unwieldy (and take twenty life points with it when they couldnt keep up)
The one innovation was that, while Innistrad only had DFCs that were a creature on both sides (and one planeswalker on both sides at mythic rare), Dark Ascension had two DFCs that started as artifacts, one of which wasn't even a creature on the back face
it will remain firmly in our sights
