Same game, 4:3 with Ambassador/Sea Hag but now the other eight are random. What needs to be on the board to NOT open with A/A or A/SH?
Again, if you are second and see his buys how does that affect your buys?
Normally I'll prefer Amb/Amb over Amb/Hag- if Ambassador is out chances are I'm just going to ignore the Hag period- they're both terminal, and Ambassador is both stronger
and counters Hag very well. There are very, very few situations where I'd take Hag but not Ambassador.
There are a few scenarios where I'd skip the Ambassador entirely, mostly involving Chapel, Possession, or Gardens. In fact, I would consider an opponent who opens Ambassador (while I'm second) to be a strong incentive to go Gardening if there's really any support at all. For example, Horse Traders/Gardens is marginal by itself, but it's helped tremendously by opponents' Ambassadoring.
It's even possible to win with Gardens
on a board without any +Buy or Gain, just your opponent's Ambassador. Obviously it helped that I could grab a couple Provinces with Counting House, and that my opponent kept sending me crap even after it was obvious that it was bloating my score, not just my deck.
