Well, if you insist...
Dame Looter
Each other player gains a Ruins, putting in his hand.
Each other player reveals the top 2 cards of his deck, trashes one of them costing from $3 to $6, and discards the rest. If a Knight or a Ruins is trashed by this, trash this card.
Action - Attack - Knight - Looter - $5
EDIT: sorry. Really bad idea. Who would buy it when you have other looters out?
