I used to play
See Beyond in Vintage a few years back. It was decent, but nothing to write home about. It was certainly useful to be able to reshuffle Tinker targets and Oath of Druids targets, alongside oddities like Gaea's Blessing and Dragon Breath. See Beyond being blue is a nice bonus, too.
I can potentially see how Tormenting Voice could be more useful than See Beyond in a deck based around Goblin Welder, but not being able to pitch it to Force of Will is somewhat of a downside. It's too bad that the discard portion is an "additional cost," otherwise an individual could cast it with no cards in their hand and just draw 2 cards with no downside.
I think that, currently, Night's Whisper is still more useful than either of these cards, though.
