Apart from Miracles (which isn't as favored as it used to be) and Stoneblade type decks, the deck has no super good matchups thanks to DTT.
Elves can beat you through pyrokinesis quite easily (assuming you even draw it at some point), the Grixis decks tear you hand apart with Cabal Therapy + Young Peezy, whilst killing you with either tokens, gurmag angler or both, and as for the combo decks... lol.
Goblins is very even-good against a lot of fair decks, but I imagine that my win percentage against them is high because of a: my experience with Goblins and b: my opponents inexperience against Goblins . That said, I haven't really played Goblins seriously since DTT became ubiquitous so I imagine my win percentages against those decks wouldn't be the 85%+ that it was.
Death and Taxes pretty much says "anything you can do, I can do better" to Goblins. If you're not playing Recruiter-Taxes, save your money and buy Imperial Recruiters instead of buying into a deck that whilst super awesome and fun to play, is just really bad against the vast-majority of the top decks right now.
If DTT goes away, I think the deck goes back to being a Tier 2-3 deck. If we get recruiter we become tier 1.5 overnight. As for now... we're like tier 500.
