I haven't seen this mentioned anywhere, but here's a basic strategy that invokes Transmogrify and Province.
Buy up transmogrifies, and buy provinces early. Turning estates into silvers or duchies into gold helps here. Important thing is to maintain a short-term VP lead.
When you have a lot of transmogrifies on the tavern mat, use them to end the game with a province in hand.
How effective is this strategy? I bet it could be refined further, for how to play, how many things to buy, etc.
