I've said it before and I'll say it again: People who think Outpost is crap don't understand Outpost
Is either Wharf (with +actions) or Caravan (alone) available? Outpost is probably good. Is it remotely conceivable that an even barely-functional double-Tactician engine could be built? Outpost is probably good. How about Menagerie? Minion? Sure, don't buy it if you have a deck where a 3-card hand isn't likely to go anywhere. But man, believe me, it is just
obscenely great in Wharf engines and double-Tactician decks, and it's pretty good in a lot of other circumstances too. Like, would you enjoy having two full turns during the endgame for each turn your opponent gets (assuming they don't follow along)? Outpost may be for you!
I gain Outpost more than a quarter of the time, with a positive "effect with". It's not even in the top 10 most situational cards.
