yo Specs -> Choice Specs in the set name
I would add some of the teammates in Scarfwynaut's thread that PK Gaming linked, as there really isn't much in the way of partners in this analysis.
Checks and Counters needs SubCM Latias, SubDD Dragonite, SubDD Gyarados, Kyurem-B, Magnezone, Thundurus-T, HP Electric / Ghost Keldeo, Volcarona, and Tentacruel.
The sets themselves look good, just remember to put space between slashes like / this / and / this.
