Here we have an artifact which enables an essential function: Draw. The first thing

that you'll notice is that the cost is heavy, and the card only allows a single draw per

turn (without untap abilities). Why would you use it? Well, another set of cards

featured in this set was the Urza's land-types. These non-basic lands, when combined

in a set of 3 unique types (Mine, Tower, and Factory), yield abundant generic mana.

Therefore, you might play a heavy artifact deck, and use your superfluous mana to

draw extra cards. It's an old strategy, and by today's standards, probably wouldn't

compete - But, given a proper set of restrictions, playing with that sort of deck could

be a lot of fun. I'll reiterate the necessity of restrictions, over and over, that would

certainly enhance the quality of play in professional tournaments. With the current lack

of rules for formats like vintage or legacy, those tournaments don't bear any real

relevance to the mind of a thinking man - Why bother? Everyone just looks to take

advantage of the natural flaws in the game design, anyway. The practice of this "art",

is really just con-artistry, and neglecting to acknowledge that fact is irresponsible.
