IDEA: Planeswalker with a "Skip your draw step" static ability & {+1} that just does something minor like gaining 1 life... but their minus is (possibly a less-wordy version of) "{-X} Look at the top X+3 cards of your library. Put one or more of them on top of your library in any order, one or more of them on the bottom of your library in any order, one or more of them into your graveyard, and the rest into your hand. You lose life equal to the number of cards put into your hand this way."
Since it's paying loyalty, not sure that the life payment is necessary. Compare to Jace, Unraveller of Secrets, which is a 5 mana permanent that just lets you to +1 to scry and draw.
It seems like what you're considering here is a card that lets you dig, keep a bunch and throw away a bunch.
Have you looked at Moonlight Bargain?
