Won with 0 rerolls (and the lowest "tools played" posted so far, although someone could get 0 if they tried of course).
Now that I know the final goal is 300 in 6 turns I can play tighter in the future
0 tools used would be incredibly difficult. you'd have to hope for an aquifer on your first shop just to be able to scale without prospect
ok then i'll do it
got it, 0 tool use 0 rerolls. (yes you're right i got aquifer first)
