Hmm. Sadly there are rules problems here: you never have to find something when searching for a card with any criteria, so you don't have to exile anything your opponent names (or even anything you name) from libraries. So it'd have to allow both you and each opponent to search all libraries... which is really painfully fiddly.

An alternative that's also really fiddly, based on Guided Passage:

> ...Each player reveals his or her library, hand and graveyard. Exile each revealed card named this way. Then each player shuffles his or her library.

This approach... isn't much better. It's like it gives everyone a Selective Memory. No opponent will ever remove anything from their deck unless they want to (because again the player doing the search doesn't need to find anything unless they want to), so this is basically worse than Selective Memory because you're removing less stuff from your deck, and the opponents get to optionally remove stuff from their decks too.

(EDIT: At the time I wrote this comment, the card said "Each player searches his or her library..." which has the problem I describe above. Now that the card has been edited to say "Each player reveals his or her library..." it works fine.)

It's not for you. It's for your opponent. Akin to Slaughter Games
