Well, not infinite. If you don't have a way to gain life, you get 19 uses before you die. But that means potentially a ton of draw power in one blast, but if you don't manage to get a winning hand out of it you're probably fucked.

The cost of 4BB is the big knock against it. I think 6 mana is kind of heavy by combo bullshit standards, but it's been a decade since I played.

Edit: As someone else said, it also lets you draw out of turn so you can go digging for a response to your opponents moves on their turn too.
