In
this game the trasher was Salvager, but this principle could probably work fairly well with any trasher where you really just want to trash Estates and then big cards for a huge payout. Since your trasher doesn't want to really touch your Coppers, your Journeymen can just name Copper and once your Estates are gone skip everything you don't want. And when you still have Estates, it doesn't matter that you're drawing them as they still provide +$2 or something like that.
Also in the same game there was some cool stuff with Grand Market and Salvager and Merchant Ship and IGG. Pretty cool game.
