It seems to be a common misconception that Intrigue has "a lot of Attacks". Like, in
this what-expansion-should-I-buy thread, the poster says maybe he shouldn't get Intrigue, because "there are so many attack cards"; I feel like this happens a lot.
But Intrigue has fewer Attacks than either vanilla Dominion or Seaside (or Dark Ages)! It has the same number as Cornucopia (if you count Followers) or Hinterlands (if you count Ill-Gotten Gains).
I guess when people think Intrigue has "so many Attack cards", what they're really thinking of is how Intrigue has
the most annoying attack cards:
two trashing attacks (which as Donald has said people don't seem to like much), the only discard-your-whole-hand attack (which means it's harder to plan your upcoming turn), and the aptly-named Torturer. So their estimate of the
number and
severity of Attacks in Intrigue is thrown off by their memory of the emotional response to those Attacks, I guess.
Meanwhile, as usual, the consensus of the thread was that the expansion he should get to play with his friends who don't like Attack cards is the one that includes Ambassador, Ghost Ship, and Sea Hag.
