Aristocrats takes its name from Falkenrath Aristocrat and Cartel Aristocrat, its two namesake allstars. The idea is simple: sacrifice your own creatures on purpose and profit every time one dies. Most pieces fill one of three roles, whether that's cheap fodder, a sacrifice outlet to cash creatures in at will, or a payoff that triggers on death.
Viscera Seer gives the deck a free, repeatable outlet, and every creature it eats sends Blood Artist's drain toward an opponent. With Teysa Karlov out, those death triggers happen twice. Token makers like Bitterblossom keep fresh bodies coming, while persist and undying creatures return to be sacrificed for profit again.
