When building with Wisp Gard, I wanted to use it with something that could capitalize on Steels being burned (Scizor, Metagross, Skarm, Ferro, Klefki) Out of the two potential options, I chose to go with SD Weavile. After Scizor is burned, Weavile can actually beat it via +2 Knock Off+Ice Shard

Gard & Weavile are extremely weak to Pokemon such as Bisharp, Scarfers (Tran / Jirachi / Tar) Diancie, other Weavile, Gyara forms. Scarf Keldeo helps deal with all of these, while also being a one-time switch in to Kabutops / Crawdaunt. Defensive Landorus was then added to fix the general weakness to Ground Spam / physical attackers like Excadrill, Zard X, Talon, Pinsir, Lopunny and Metagross, while also providing rocks for the team+momentum for the Offensive mons

At this point, the team was slightly annoyed by Rotom, Keldeo and Manectric. Hazards also annoyed Weavile, so I put Latios w/ Roost on the team. Usually, the aforementioned mons it checks are paired with Pursuiters, but Weavile can take advantage of say a Scarf Tar and set up on it then proceed to possibly win the game

Finally, I decided to use Heatran in the last slot, which gives us a pivot for Wisp spammers, semi-check to Thundurus (Chople allows you to take Focus Blast), Torn-T / Zard Y lure, Serperior check, Clefable / Scizor check. I say "lure Torn" because after a Superpower, Edge can kill it due to the -1 drop. Chople is also clean for luring opposing Gardevoirs [:

Other: Speed IVs on Landorus is so that you can U-Turn after other Landorus. Speed on Heatran outruns Max Adamant Scizor, while the rest of the EVs are thrown into SpA for a bit of power, along with bulk to take hits a bit better. Earth Power Diancie can be a slight pain, but most tend to carry HP Fire, and Keldeo can check / Landorus can take a single hit and KO in return
