0217 Ursaring

Ursaring's primary role in Ultra and Master League is as a counter to Giratina-Origin (and to a lesser degree Giratina-Altered), double resisting Ghost-type attacks, so Shadow Claw is your fast move of choice.

There are better options for Counter users, and you still have Close Combat as useful coverage for the many relevant Steel-types. Play Rough rounds out the moveset with a nuke for Dragons as well as for Ursaring's Fighting-type counters. Hyper Beam demands too much energy to use. 

Ursaring performs quite well against Ghost-types thanks to its double resistance as a Normal-type Pokemon. However this is mostly the only reason to pick Ursaring, since it struggles against the rest of the meta due to its poor bulk and inefficient charge moves. 

Up in Ultra, where Giratina reigns supreme, Ursaring begins to pick up a powerful niche, doing a great job at walling the renegade dragon's mono-Ghost moveset and swinging back for super effective damage with Shadow Claw and Play Rough. However Ursaring tends to struggle against the rest of the meta, and Dark-types have an additional advantage against Psychic-types specifically. 

In Master League, Giratina-Origin becomes even more prevalent than in Ultra, which gives Ursaring another bump in utility. That said, as before, it's still a niche counter, which limits its utility.
