Praetor's Grip - Single Card Discussion

This card was spoilered in japanese today and kindly translated by a teammate:

Praetor's Grip -1BB
Sorcery

Choose an opponent. Search that player's library for a card and exile it face down.
That player shuffles his library. As long as that card is exiled, you may look at it and play it.

That's sick! A Grim Tutor that also strips opponent from key-cards and he doesn't even know that one! Haha! Moreover that card is safe from discard and unlike similar cards the removed one can be played at any time of the game, granting you very flexible plays.

Is this card the upcoming reason to sleeve-up dark rituals in vintage again? Is a first turn time vault snatch the backbreaker for the new turbo tezz? Will the granted access to an additional Tinker, time walk, Ancestral Recall, Time Vault or will turn the tide?

Time for discussion!
