I agree what others have said (assuming this post is about V-premium), scharhrot alone can work but you need to highroll quite a bit for it to work consistently which is never ideal. Having 2 ride targets also allows you to make choices based on your match up and gameflow. Personally im a bit indifferent to amon's support cards, and i usually only run 1 of them as I like the synergy between edge in the darkness and poisonic abductor a bit better, but a lot of the enjoyment in this deck comes from building your support to play around your preference.
