My new favorite no-cost-reduction Inheritance target: Encampment. It's drool-worthy.
Depending on your priorities and your opponents, you can use the Estate-Encampments at the beginning of your turn in case you have to put them back into the Estate pile and rebuy them.
Forget Estate-Ironmongers and Estate-Magpies. It's hard to beat +2 Cards, +2 Actions. Encampment would be an overpowered card if there were more than 5 of them. 13(17) of them is a LOT.
I managed to do this in a game with good trashing, +buy and Windfall. Yeah, I know. I also snagged the reset of the real encampments first before my opponents could inherit one, which doesn't take long since there are only 5 and Inheritance removes one. This was in a kingdom with no other draw. And a bunch of terminals and no other Villages. Ouch. One Windfall is plenty: Every subsequent turn was draw deck, Militia attack, Workshop an Estate-Encampment, Golds and two Plunders for points/coin, buy two Provinces and an Estate-encampment, repeat. It never stalled, even after buying 10 Provinces.
