Well, for starters, a blind mst is not a "logical move", it is a gamble. (especially vs a deck maining artifacts)
to follow up on that, nobody was insulting you yet you felt it necessary to insult us for disputing that. instead of blindly arguing that you are correct try to see from the opposite end of this and realize that you do not "know" what an opponent's sets are, unless you just saw their hand, in which case, you still don't "know" which is which unless they had just the 1 s/t to set. You can try and pretty up that argument but a blind mst is a blind mst and vs HAT its not a great idea.
