Derringer, for those unfamiliar, is a format in which deck building is limited to 1 of a card title. You can still play 4 of a value. Our local game store is doing a Derringer event, so I whipped up some basic archetypes for the format in case anyone comes to the database looking for ideas.
This is a pretty basic Dogs aggro deck, full of clubs and lookin' for a fight. Structure is 5/8 full houses, with a potential for straight flushes on clubs (3-8). It has some amount of horse tech, mostly as a counter to other horse tech but can also capitalize against decks that run no horses.
