Carnarium Concerto

Each player discards their hand, then sacrifices
non-land permanents equal to the number of
cards they discarded. If they cannot sacrifice
non-land permanents equal to the number of
cards they discarded, they lose 3 life for each
card they discarded without sacrificing a
non-land permanent.
The ultimate goal of every Rakdos performance is to
win the attendance of Rakdos himself.
