Basically what you do is get the 2 plot twist and augmented into hand and do that infinite combo. Other pieces are their either to disrupt combo or aggro. If you can get your weapon into play before you go off so that every turn if you had a demon in your hand you could get it into play for free allowing you to build a stronger board then a 3/4. Chromagus and the Demonlord help you win but really just increase value. Also getting infinite health with 6 drop demon that restores 4 health is useful
