Zakiir the Summoner

When this spell is cast, create three 1/1 red and
black Demon tokens with flying.
{b}{r}{t}: This ability costs an extra {b}{r} for
each opponent. Put a Fear counter on target
player. Players with Fear counters may not attack
you as long as you control a demon.
At the beginning of each upkeep, if the turn
player has a Fear counter, sacrifice creatures
equal to the number of Fear counters in the
game or exile Zakiir.
Fear is control.
