As I am somewhat of an outsider still to the Type 1 scene and only recently come back in I may still have an outsiders perspective. That is the only apology I will give for this thread.
The metagame as we have seen it has been shifting at this very moment towards decks that run collections of wins, but how many wins are these decks truly running? What follows are deck lists directly from the Vintage Encyclopedia with their win conditions emboldened.

So after looking at the actual threats, things that kill/deck, we can see that each of these following decks is reliant on a silver bullet like approach. Utilizing most of their deck for resources to build up to the win or to secure board position. Whether that being counters or discard or mana denial they all work in some form to prevent the enemy from utilizing their own spells (duh). Where does this leave us? We see that the board develops beyond our control by the opponents denial effects and that is troublesome. But all of these decks rely on their win conditions for the actual win. If the tinker is stifled the opponent won't lose automatically, it just becomes harder for them. So out of this mess of an article I come with a suggestion. It's a bad card against decks with multiple win conditions, IE stax, goblins, and the like. But what it makes up for that is the readily availability of its ease in casting.

Search target player's library for a card and exile it. Then that player shuffles his or her library.
Pros: Blue, Eats silver bullets, always finds something good to get rid of, equal in Theoretical CA, cheap, decent sideboard alternative, lack of wishes in current meta raises effectiveness.
Cons: Misdirectible, will not affect hand position, loses ground in techinical CA.
I hope this will help in someones build of fish for the metagame.
