>>12082643Hi. I'm probably a little late here, but the core you mentioned uses a special Sheer Force Landorus with Rock Polish, Keldeo with either a Choice Scarf or Expert Belt set and Choice Band Tyranitar. The general idea behind the core is that Keldeo and Landorus can both soften up or outright KO each others checks and counters. A lot of them (Latias, Jellicent, Celebi without Baton Pass) can also be Pursuit trapped by Tyranitar.
Good "filler" concepts to pair the core with are Terrakion and an interchangeable defensive core (at least one rain counter!) or Dragon + Steel + X (i.e. Scizor, Latios, Celebi).

Definitely a great team to steal.

>>12082685Tyranitar/ Landorus/ Keldeo is THE core right now, but the Nyandorus/ Rotom-W one you mentioned has been getting some hype as well lately. Some people include Jirachi as well.
Cores around Celebi have recently been seeing a lot more use as well. Think along the lines of CeleTran or NP/CM+BP Celebi and Keldeo or Thundurus-T.
If you are looking for an "anti-meta" core capable of abusing more common cores try CM Latias paired with anything that can abuse Tyranitar and Scizor.
