This team is based around using the volt-turn core of Landorus-Therian and Tapu Koko to get in your hard hitters.
Mega Medicham was the focus of the team. I added Hoopa-Unbound to take advantage of pokemon like Mew, Clefable, Reuniclus, And Mega Sableye. The next addition was Tapu Koko for speed and to gain momentum to bring in your hard hitters. Specs Tapu Koko is to annoy offense to hell and back and annoys balance a bit with volt switches. Latios was the next addition for hazard control and some actual speed control. The defensive core of Landorus-Therian+Ferrothorn was added to give switchins to pokemon like Zygarde, Mega Loppuny, Ash Greninja, Mega Mawile, and opposing Tapu Koko. The other reason for Ferrothorn over something like AV Magearna is to provide hazard support for my wallbreakers.
