At first it looks boring; no +buy or gains, so it's going to be some Upgrade into BM thing, right?
But, of course, there's Tomb. Turns out building an engine that can upgrade a 3$-card all the way to Province each turn is quite fun. This board is probably quite rare in allowing all steps form $3 to $7 in abundance. I could even have gone down to $2 (probably should have in a mirror - winning the Upgrade split would be critical there), but I was worried about long-term stability.
