Ok, similar question. Your starting deck is now 7 Provinces; no other cards. Your opponent's starting deck is 1 Monument. Who has the advantage?
Again, board is going to matter. If there's an Embargo, Province player probably has no chance. (Turn 1, play Monument, buy Embargo. Turn 2, Embargo Copper.) Any good 2's are going to be great for the Monument player of course.
My guess is that most boards will lead to a Monument victory. If there's any Village at all, it will be easy to get to the point where you are playing 2-3 Monuments every turn (assuming Monument is in the Kingdom as well).
My guess is that most boards will lead to a province victory. Think about it, how many duchies can the monument player safely buy while still being able to assuredly get the last province before his opponent? He needs the game to last 36 turns, -3 times the number of duchies he can nab, plus the number of turns he's going to miss playing a monument. In kingdoms with a village, it'll be close, maybe. And in a few cases, monument has it cold. But usually, I don't think so.
Edit: and with remodel or salvager or something along those lines, forget it.
Definitely wasn't thinking about Remodel or Salvager. But without those cards, Monument player can do something like this:
1. Buy Pawn
2. Buy Silver
3. Buy Duchy
4. Buy Duchy
5. Buy Duchy (at this point, he has 6 cards in deck, but 1 cantrip so still playing Monument every turn)
6. Buy Hunting Party (Lab could work too, but not as well).
7. Buy Duchy (now, she has a very slight chance of drawing 4 Duchies and a silver)
She can alternate HP/Lab and Duchy; with average draw luck, after about 13 turns she will have 7 Duchies, and 13 VP tokens.
Next 3 turns, purchase Silver, Silver, Province.
Only 16 turns...
(7 * 3) + 16 + 6 = 43 points.
What can Province guy do in 16 turns? Hard to say... but his first 5 or more turns will probably be buying nothing but Copper, or Pawn if he's lucky.
