Thoughts: Just like Lando-T, it is really versatile and splashable. It is a really important Pokemon, in order to check both Landorus forms, Groudon, Infernape, Moltres, Tapu Bulu and Venusaur. It's speed gives it the ability to offensively check the already mentioned Pokemon with the additions of Reshiram, Zarude and both Kyurem forms.

Checks: Steel-types do well against its STAB moves, but they have to be careful in regards of their weakness to Aura Sphere and Mystical Fire. Fini and Florges are the best checks to it thanks to their typing and special bulk.

Partners: It appreciates help from Pokemon like Venusaur, Infernape, Kyurem and such to beat its checks, but other than that, it fits on many teams.
