I'd just like to say that Specs Zoroark with Trick makes a much better partner to Heracross, since it can Trick it's Specs to a wall, or just hit Hera's counters hard.

This core is based around Durant, who synergises incredibly well with Chandelure. Chandy can come in on fire type moves thanks to Flash Fire, and seriously injure the mon that is coming in next.
Durant brings with him some serious fire power, 2HKOing even Gligar after SR and a Hone Claws. Snorlax is easily dealt with as well-so is Umbreon and Porygon2-Chandelure's biggest counters. All 2HKO'd. Durant's counters, like Dusclops, are dealt with through Chandelure, and Flash Fire absorbs Will-O-Wisps aimed at Durant.
One thing they both struggle with though is powerful hits. Suicune provides some good bulk and deadly sweeping capabilities with Calm Mind and Roar, as well as being a good general tank, in comparison to Chandelure's paper thin defenses and Durant's ridiculously low special bulk. Suicune can also weaken physical walls for Durant, like Gligar and Cofagrigus, while both Durant and Chandelure can destroy Roserade-one of Suicune's top counters. Suicune also takes care of Nidoqueen-who is another top check for Durant.
This core is ruined a little bit by Raikou though, so Rhyperior or Snorlax or Swampert(although he doesn't synergise that nicely with Suicune)will work nicely on the team. Two of these can give SR support, and one can tank special hits(using both Rhyperior and Snorlax on the same team is never a bad idea-Raikou is a major threat).
