Your choice of lands seems kinda random to me.. Tolarian Acadamy is great, but in this deck it doesn't help all that much because there are no blue cards.

yeah, the lands are a little too scattered out on what you want to have going on here. and, btw, this format of an artifact deck is not very impressive, not to be critical, but when ppl post a deck being the "best ever" it damn well better be. but again this is an ok start, there are a lot of things i can suggest but i am not sure what you're trying for if it's only affinity? or.. idk... check out my artifact deck, Platinum Dawn maybe for a few quick ideas. B + artifacts is a fun combo, but i prefer U/W. nice work, 5/10

rate / comment my newest success, Defiant Lure ... thanks

i would add bitter ordeal, with all that artifact sacrifice, this card can be really helpfull

maybe some
nims.. like nim shrieker, nim lasher, nim shambler

those cards aren't a must-have in this deck, but i would consider to find a place for some of those =]

plz comment on one of my decks i will be really happy =] thx
