The Lost Caverns of Ixalan

Ojer Pakpatiq, Deepest Epoch | Legendary Creature | God | Flying Whenever you cast an instant spell from your hand, it gains rebound. (Exile it as it resolves. At the beginning of your next upkeep, you may cast it from exile without paying its mana cost.) When Ojer Pakpatiq dies, return it to the battlefield tapped and transformed under its owner's control with three time counters on it. | Chris Rahn

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

Ojer Axonil, Deepest Might | Legendary Creature | God | Trample If a red source you control would deal an amount of noncombat damage less than Ojer Axonil's power to an opponent, that source deals damage equal to Ojer Axonil's power instead. When Ojer Axonil dies, return it to the battlefield tapped and transformed under its owner's control. | Victor Adame Minguez

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

Sovereign Okinec Ahau | Legendary Creature | Cat Noble | Ward {2} Whenever Sovereign Okinec Ahau attacks, for each creature you control with power greater than that creature's base power, put a number of +1/+1 counters on that creature equal to the difference. | Victor Adame Minguez
