Anowon, the Ruin Sage
Legendary Creature — Vampire Shaman
At the beginning of your upkeep, each player sacrifices a non-Vampire creature of their choice.
"So many have died in search of that map. And now it appears in the hands of the arrogant child Chandra Nalaar."

When the triggered ability resolves, first you choose which creature you'll sacrifice (if you control any non-Vampire creatures), then each other player in turn order does the same, then all chosen creatures are sacrificed at the same time.

If a player controls no creatures, or if all creatures a player controls are Vampires, that player simply doesn't sacrifice anything.
