Trumpet Blast

Attacking Creatures get +2 +0 until end of turn.
Have seven priests carry trumpets of rams
horns in front of the ark. On the seventh day
march around the city seven times, with the
priests blowing the trumpets. When you hear
them sound a long blast on the trumpets, have
the whole army give a loud shout; then the wall
of the city will collapse and the army will go up,
everyone straight in Joshua 6:4-5
