Wasteland
$6
Worth 2VP for each empty supply pile
I am new to this card creating business, and I wouldn't be surprised if something like this has already been put forward.
Clearly, this is worth the same as province if you end on piles. I'm not sure what fraction of games deplete one pile + provinces, but in those games Wasteland will be worth 4, like Fairgrounds usually is. Sometimes it'll be worth 2 and you won't buy it. There will be rare cases where you can get the last province/colony and empty another pile in one turn, but this is hard to pull off and worth rewarding.
If it's too strong, you could make it worth 2 +1 for each empty supply pile, which would make it strictly better than duchy but would require a strong duchy/other advantage if you're forgoing provinces for Wasteland. I don't think changing the cost to $7 is feasible.
