I've created two base layer teams for Double OU Gen 9 where I used a 2 & 2 & 2 format for grouping my pokemon. Each grouping is in order. At the very least for the 1st team I want to keep Honchkrow and Serperior and for the 2nd I want to keep Basculegion-F and Scizor. I felt like I made a good base-layer for this team, but because I'm still relatively new to the competitve format I'm unsure of how to upgrade. All suggestions are welcome and appreciated.
