1 button unholy?

Anyone have a good one button unholy that I can manually choose when to APOC and manage my other cooldowns?? I will try creating a profile of my own, but I fear I’m gonna be horrible with it or just not grasp it. Lol

Why not just use a Weak Aura or Trufi’s that tells you when to use a CD or when it’s up?

I plan to manage my own cooldowns. Just getting the builder/spender down to a 1 button would be good. Had a solid one pre patch 8.0 but can’t replicate it ???
