Astrid, the Eternally Famished

At the beginning of your endstep, if you gained
2 or less life this turn, sacrifice Astrid.
Whenever you gain life, each opponent loses
that much life.
"Vampire servants are much too self-centered and
lazy. On the other hand, human servants wouldn't
dare be disobedient lest they are eaten." -Astrid, the
Eternally Famished
