I first added sub roost Articuno and standard Vibrava since that was the core this week. Then I wanted an electric immunity, pivot, and Rotom-Frost check so I ended up adding Chinchou. Next I added Rapidash for offensive presence and as my revenge killer. Then Stoutland was also added since its the best mon in the tier. Lastly Mawile, was added as my rocker, normal check, and bird spam check. Enjoy guys [:
