I am looking for someone to help me with building a demon deck. My friend has one that is really OP and i would like to make one for myself.
I have a lot of black cards so hopefully I have atleast some of the cards i need. If not i will buy what i am missing.

I like fast pace playing,and cards that I can combo.

Some of the cards i already own are:
Dread Cacodemon
Abhorrent Overlord
Desecration Demon
Bloodgift Demon
Rakdos, Lord of Riots
Demonlord of Ashmouth
