Yhim, Silent Supremacy

At the beginning of each opponent's upkeep,
place a 2/2 Germ Token with deathtouch under
their control. Germ tokens must attack each turn
if able and can only attack players that do not
control Yhim. If a Germ Token destroys an
opponent's creature, Yhim, creates a 2/2 germ
token with deathtouch under that player's control.
At the beginning of each end step, you may choose
to force any number of opponents to sacrifice all
germ tokens created by Yhim, and lose 3 life for
each germ token sa
