Dednap's Votary

Deathtouch
Whenever a creature is killed by Dednap's Votary, you may put a +1/+1 counter on all other Cultist creatures you control. If those creatures are black and green, then put two +1/+1 counters on them instead.
Devoted and driven by Dednap's call. By fear, yes. By admiration, most definitely.
