Biomass Processor

When Biomass Processor enters, exile another target creature until Biomass Processor leaves.

Supremacy — At the beginning of your end step,
if you've cast a creature and noncreature spell this
turn, put up to one creature card exiled with Bio
-mass Processor into its owner's graveyard. You
gain life equal to its mana value.

As Dormu's desperation grew, life itself became a resource to his machinations.
