Part of me questions the value of the Wraths although you don't have anything else to really deal with a BIG threat.
I'm not totally sure what's available in Modern that would work well here but with Flanking a couple good abilities to "add on" might be
Provoke and Trample.
Provoke could force someone to block a creature with flanking and then take that -1/-1 without much recourse. Trample of course walks over the weakened creature but perhaps more importantly would mean that all damage could go through if Flanking kills any blocker before you even get to damage.
