Mega Scizor, the Pokemon replacing Mega Diancie. It also sort of replaces Talonflame due to the fact that it has decently strong priority (but of course nothing will replace that monster). It gets decent recovery and Swords Dance in case I need to pull off a sweep with Mega Scizor. It gets a debuff due to its lowered HP but I doubt it's much.
Scyther, Scizor's little brother. It has Eviolite so it can take attacks and since you should pretty much always run Eviolite on NFEs. It has great STAB, amazing attack, and Knock Off to, well, knock off items, and Quick Attack to hit people hard with 180 attack. I didn't invest in attack because it already had high attack and Scyther could use the bulk.
Alakazam. It inherited 20 defense. Seems horrible, right? Well, Focus Sash and Magic Guard lets it live any hit so not really. It has neat coverage, too.
Meet Serperior. This thing was major in GotG Gen 6. The main thing holding Serperior back besides its coverage is its bad Special Attack in OU, but here, 180 not only gives it high special attack, but it somewhat alleviates concerns with coverage. And with Contrary and good speed, this thing is hard to beat.
Meet the God, taking up the special defense slot. This thing isn't meant to do much. Just setup rocks and remove the lead's item. Maybe hit with an Espeed or a hard Psycho Boost or something.
Now meet the star of the team, basically one of the most important members and ultimate Talonflame counter: Rhydon. This thing is just amazing with 150 speed inherited from Deoxys-A. With Eviolite it can setup Swords Dance easily while being able to take a hit and then demolish with its STABs, and use Megahorn if necessary.
