Okay, so recently I had a game where I saw scout and great hall on the board and used them to put together a nice draw engine that would let me cycle my deck, play my witch pretty often, and buy a bunch of provinces without slowing down. I thought I was pretty clever, and I'd done it before too. (Both were IRL games, I haven't played at all on iso lately.)
Since I hadn't read anything on these forums or the blog about when something like that is worthwhile, I tried to play around with simulators or figure it out - how fast is it, when it's wortwhile, or something. I knew that it wasn't good very often, and that the best way to play Scout is usually "don't", but I suspected that going for a Scout/Great Hall drawing engine would be worthwhile if:
1) There's a powerful attack around, like Witch, worth building a cycling engine for
2) There's a way of gaining Great Halls quickly so you don't spend too many buys on them (ironworks, upgrade, remake, maybe workshop or remodel or bridge)
3) Trashing, so coppers don't get much in the way.
But even using those things, simulator kept telling me that BM+ was better. But the simulator don't play Scout that well. But maybe it's good enough. So I figured I'd make this post.
Are there situations where it's worth getting a bunch of great halls and some scouts for a drawing engine? Does it require two dual-type victory cards in the Kingdom? What sorts of Kingdoms are there where Scout+Great Hall is clearly better than BM+? Did I just get lucky the times I went for Scout+Great Hall and thought it turned out well?
