Was Urza the Pope at one point that I don't know about? Anyway, this card's idea is alright. Drawing a card whenever an artifact you control dies (but isn't sacrificed) is nice, but having to pay for it hurts it. The fact that the artifact can't be sacrificed also doesn't help. Although, it is colourless repeatable card draw which is rare. All-in-all it's a good idea badly executed.
Pros: Colourless card draw
Cons: Triggers on non-sacrificed artifacts, costs a fair bit of mana, only one card per artifact death
