The Lost Caverns of Ixalan

Bloodletter of Aclazotz | Creature | Vampire Demon | Flying If an opponent would lose life during your turn, they lose twice that much life instead. (Damage causes loss of life.) | Antonio José Manzanedo

Broodrage Mycoid | Creature | Fungus | At the beginning of your end step, if you descended this turn, create a 1/1 black Fungus creature token with "This creature can't block." (You descended if a permanent card was put into your graveyard from anywhere.) | Domenico Cava

Chupacabra Echo | Creature | Beast Horror Spirit | Fathomless descent — When Chupacabra Echo enters the battlefield, target creature an opponent controls gets -X/-X until end of turn, where X is the number of permanent cards in your graveyard. | Izzy

Starving Revenant | Creature | Spirit Horror | When Starving Revenant enters the battlefield, surveil 2. Then for each card you put on top of your library, you draw a card and you lose 3 life. Descend 8 — Whenever you draw a card, if there are eight or more permanent cards in your graveyard, target opponent loses 1 life and you gain 1 life. | Fesbra

Vito's Inquisitor | Creature | Vampire Knight | {B}, Sacrifice another creature or artifact: Put a +1/+1 counter on Vito's Inquisitor. It gains menace until end of turn. | Anna Pavleeva

Vito, Fanatic of Aclazotz | Legendary Creature | Vampire Demon | Flying Whenever you sacrifice another permanent, you gain 2 life if this is the first time this ability has resolved this turn. If it's the second time, each opponent loses 2 life. If it's the third time, create a 4/3 white and black Vampire Demon creature token with flying. | Marta Nael
