I love this card for EDH decks since those games tend to run long. Drawing extra cards is always a good thing and, if it's caused by you missing a land drop, it allows you to dig deeper to find that land. There's not much else to say about this card aside from that. It does cost 5, so it comes out late game, but that's usually when you'll be missing land drops.
Pros: Gives extra card draw
Cons: Requires missing land drops
