Toshiro Umezawa is the first place Id put this, but it excels in both Rakdos Treasures/Artifact Burn style decks and also in non-green black decks that want a little boost of mana
the upcoming format is going to have a shortage on playable artifacts: Runechanters Pike and Witchbane Orb from Innistrad Block, a couple of Keyrunes (maybe), and from M13 Staff of Nin (?) Oh yeah, and Trading Post
Second Star to the Right 210/204 Wouldnt it be interesting if the most gorgeous enchanted of the set was a song card
Ascension If you ever thought the best card games were all rather similar, then guess again: Ascension is a deck-builder rather than a card battler

If you think there are too many legends being printed, wait until you see how many payoffs there are
