Trash for benefit
Trash for benefit (or "TfB") are trashers that provide a benefit based on the trashed card, normally based on its cost, and typically providing better benefits for trashing more valuable cards. TfB cards can typically be used both for thinning your deck by trashing junk cards for modest benefits (or no benefits), and for achieving large immediate bonuses at the expense of sacrificing a card you might otherwise prefer to keep in your deck. Terminal TfB cards are usually soft terminals; when they collide with an expendable Action, they can use it for fodder, sometimes even to gain or buy a Province.
Cards that specifically gain another card based on the trashed card's cost are remodelers.
