Boron, I think you have a tendency to discount what your opponent can do too quickly. When you post a strategy and ask for a counter, usually you get three or four counters which you immediately dismiss with a counter-counter. In practice, I really don't think it's that easy. As others have pointed out, you are presuming turn 100 and having 50+ vampire lords and being able to push dominion. First of all, how did you get to that point? Opponents aren't going to idly sit back and let you collect vampire lords without doing something of their own.
You state that Flames from Afar or Murdering Winter can take care of opposing preachers, mages, etc. Well, the same goes for them, they can use either of those spells to decimate your leaders, too. You say you will protect yours with domes, well, your opponents can too. The point is, everything you say you will use to nullify your opponent's threats, your opponent can likewise use to nullify your threats. Because each side has limited resources, it then becomes a matter of
which counter is used at which point in the game.
Having said that, I'm not trying to be harsh, and I hope that I never, ever, ever, face an opponent with 50 vampire lords.
