you may put a Worship counter on target
creature you control, then creatures you control
with worship counters on them get +1/+1 for
each Worship counter on them until end of turn.
Sacrifice Arakhab, Cult Leader; You may cast
target instant or sorcery spell from your
graveyard without paying its mana cost until end
of turn. When you cast it this way, exile it.
