Since there is no commander in vintage, that means there are 0 colors of your "commander's color identity," right? So in vintage, this is just a land that taps for colorless and has "3T: draw a card," yes?
Maybe playable, maybe not, but it seems this is the cheapest effect of this kind on a land without discard, making your opponent draw, or having other conditional hoops to jump through to draw a card.
