Funny, on another site I'm having a discussion about whether or not T&N is viable in extended now that Raffinity is dying, and somebody starts a thread about playing it in Vintage here. You'll never pull it of... why not? Because you can't race any decks. In Extended the deck's main strength is that it is fast enough to race aggro and it can compete with other combo decks because it has certain control elements that win you the game.
In Vintage it will be impossible for you to race ANY deck except maybe for Fish, but like Smmenenenenenen pointed out; you'll never resolve the Tooth against a control deck.
In all seriousness though this might work in type 1.5 where aggro is dominant, just need to combo off before they kill you.
(Extended) Raffinity takes this deck apart. Why then would Legacy decks fail at this?
