I feel like in order for this card to be great, you need to snatch a Lotus from the opponent, or other pieces of artifact mana. Otherwise you're down three mana and sure, you might get a cheap creature or Ancestral from the opponent, but 2UB to draw three cards is not that good of a rate.
I'm pessimistic about the card: I'd put it in the same category as Thada Adel, Acquisitor or Praetor's Grasp: a unique and very powerful effect, but too inconsistent against a diverse meta to be useful maindeck, and not impactful enough for the sideboard.
