Magic The Gathering Cards of types 'Vampire' and 'Demon'

Flying When this creature enters, if you cast it, each player sacrifices all other creatures they control. Then each player returns all creature cards from their graveyard that weren't put there this way to the battlefield.

Flying If an opponent would lose life during your turn, they lose twice that much life instead. (Damage causes loss of life.)

Flying

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.

When Lord Xander enters, target opponent discards half the cards in their hand, rounded down. Whenever Lord Xander attacks, defending player mills half their library, rounded down. When Lord Xander dies, target opponent sacrifices half the nonland permanents they control of their choice, rounded down.
