I built this team to support Mega Alakazam + Magearna, which is one of the best offensive cores available right now, in my opinion at least. Mega Alakazam easily takes advantage of Toxapex, which is the only common Pokemon that reliably walls FleurFocus Magearna. It also wears down Celesteela, which is an awkward match up for Magearna if Celesteela is not weakened. Toxapex was added for its Toxic Spikes support, it also reliably checks Pokemon like Volcarona, Mega Lopunny, Keldeo, Magearna, and Greninja. Heatran sets Stealth Rock for the team, checks Tornadus-T, Celesteela, and Clefable, and can also burn Toxapex for Magearna. Magma Storm could be run to help with stall, but Lava Plume is generally more reliable, and the added burns are nice. Protect is chosen to scout Choice-locked Kartana, but Taunt could also be run in tandem with Magma Storm. Tapu Bulu checks Pokemon like Mega Alakazam, Tapu Koko, Zygarde, and Tapu Lele reliably. 96 Speed EVs are run to outspeed Adamant Crawdaunt. Protect is chosen to scout out Choice-locked Kartana once again. Landorus-T provides mandatory Defog support, it also provides pivoting support and blocks Volt Switch.
