I will just about always try to find space for a Condemn when the colors I'm using allow for it, it's just so helpful, especially against commanders like Derevi, Empyrial Tactician.
Well, I feel if nothing else cards like Flameblade Adept will give help produce a new competitive Madness deck alongside Noose Constrictor and Fiery Temper, probably resulting in a Jund/UBRG colored deck. Overall I don't find it really that impressive as of yet, as no cards really stand out as exceptional, but then again we just had the expertise cycle and Fatal Push, so...
EDIT: Gideon of the Trials looks really good.
