Give me my worst

[Jacques]

I was talking to a friend a few days ago about Gifts Ungiven.  This got me thinking about tutors that gave your opponent some control over what you got.  So I'm sitting there trying to figure out a new way to do.  Obviously there's the problem of them just giving you a land every time you get it.  Where as this may be useful in some situations, most of the time it'd be bad.  I'm tired of seeing "Take X cards from you library, and opponent chooses Y of them that you get" type cards.  I want your opponent to have access to your library.  Ultimately I came up with this:

What've I got?
{x}{u}
Instant
Target opponent searches your library for a card with converted mana cost x or more.  Put that card into your hand, then shuffle your library.

The x clause is mainly to prevent them from giving you a land every time, but also to make it slightly custom tailorable.  I could see having it make them give you a card with cmc of x, though I'd prefer not to if at all avoidable.  Obviously, letting your opponent have complete access to your library is a rather large drawback.  They'll know what you're playing and they   could even figure out your hand given enough time.  I could see a weird combo deck with all low cost spells and one or two high costing finishers.

Current Wording:

What've I got?
{x}{u}
Instant
Target opponent searches your library for a card with converted mana cost x or more.  Put that card into your hand, then shuffle your library.

One thing I notice about this is that it's really really hard to find things of CMC=1 because they'll just get you another of these tutors. Maybe put "not named ~this~" on it somewhere?

Other than that I like this a lot.

So are you also suggesting I make it say "with cmc equal to x"?  Because right now, it says x or more.

I would like the CMC=X version but you don't HAVE to. It should get that clause even if you don't - someone might want to use it in some arcane Kobold deck or something.
