Horrorscale Despot

When Horrorscale Despot enters the battlefield, proliferate. (You choose any number of permanents
and/or players with counters on them, then give each another counter of a kind already there.)
Whenever you proliferate for the first time each
turn, you may have each player sacrifice a
creature.
Naga society is ruthlessly meritocratic. Those that rise
to the top do so by both proving their worth and
ensuring their peers can't.
