Oh boy, huge changes in rules.
As others have noted, Death Cart, Embargo and Pillage are changed, but there are many others that were untouched. Previously those three cards worked normally with BoM/Overlord/Inheritance, and were super-good with Necromancer/Captain. To avoid too much super-goodness, Donald changed them, so now they are useless with BoM/Overlord/Inheritance AND with Necromancer/Captain (except Death Cart is gimped but not useless).
The cards that were untouched: Acting Troupe, Farmers' Market, Feast, Knights, Tragic Hero, Wine Merchant, Encampment, Experiment, Island. These are all super-good with BoM/Overlord/Inheritance now (except Island) - in addition to with Necromancer/Captain.
Some cards used to be normal with Bom/Overlord/Inheritance, and useless with Necro/Captain, but are now useless with all: Mining Village, Pixie, Treasure Map, Urchin, Page, Peasant, Distant Lands, Prince (only gimped: Raze, Small Castle)
(Obv. Small Castle can't be played with Inheritance, and Prince requires a lot of cost reduction)
EDIT: Knights were in the wrong list!
EDIT2: Distant Lands was always useless with these cards.
