Sinners' Vessel

Afterlife X, where X is the amount of life you
have gained this turn (When this creature dies,
create X 1/1 white and black Spirit creature tokens
with flying.)
Those deemed too vicious, too tainted for even the Syndicate's brutal standards to have their impure
spirits immediately indentured after execution are fed
to the Vessel-Thrulls. There, the souls face the full
weight of their lives' misdeeds, crushing all else but the desire to serve from their spectral minds.
