A tutor designed as an interrogation, and the rare case where the search is filtered through an adversary's hands. Most search effects let you reach into your deck and pull the exact card you need; this one hands the top ten to an opponent, lets them look at every one, and asks them to split those cards into two face-down piles. Then the choice flips back to you: you exile one pile and search the other, but you are picking between two anonymous stacks an informed enemy built specifically to bait you. That asymmetry is the whole design. The opponent has seen all ten cards and arranges the split to make your guess as costly as possible; you know only that whatever you want may be somewhere among those ten, and that one half of them is about to be gone for good. Loading your deck with the cards you most want to find only hands more of them to the person doing the sorting, which means it punishes the kind of stacking a normal tutor rewards. It reads as a shell game where the loss is dressed up as selection, and the repeatable activation invites you to keep feeding it until your library thins below ten and the ability simply stops. The whole thing favors story over clean advantage, the swingy, high-variance register the artifact slot was indulging at the time, and it remains one of the strangest tutors ever printed because the search you paid for runs through your opponent first.
