This team looks insanely generic but I actually had some success with this so I thought I might as well send it in. The core of Mega Manec + Garchomp actually came from a
Good Cores post and I felt like building some HO around it. I decided to use BD Azu as the main wincon for this team and I felt that it worked very well with Manectric wearing down mons with Volt Switch and Garchomp completely breaking walls for Azu to sweep. I added Bisharp because who runs HO without Bisharp? It also worked very well alongside Klefki by deterring Defog. Klefki is needed as an answer to a bunch of set up sweepers that can easily overwhelm my team as I lack a scarfer and can't outspeed them plus its really useful with Azu as it weakens teams with Spikes and TWave. And last, I needed a CharY switch in, I didn't want HW, so I went with Latios. I kinda wanted to run HP Fighting for Bisharp as I'm kinda weak to it but I'd rather have CM to screw over Gliscors and Hippos that think they can just eat up a Draco and heal off the damage. Mlops a threat but it's complete aids for HO anyway, but Klefki can usually eat up a couple of hits and pressure it with Spikes / Twave. Bisharp is another issue too, but I can usually 1v1 it with my own Bish or EQ with Garchomp it if it hasn't boosted and bluff a defensive set.
