>>44247296Tierno's team should've been;
Mr. Mime (Lv48) - Teeter Dance, Psychic, Dazzling Gleam, Focus Blast
Masquerain (Lv48) - Quiver Dance, Ominous Wind, Air Slash, Bug Buzz
Swanna (Lv49) - Feather Dance, Surf, Roost, Brave Bird
Politoed (Lv49) - Rain Dance, Perish Song, Scald, Ice Beam
Roserade (Lv49) - Petal Dance, Shadow Ball, Sludge Bomb, Toxic Spikes
Tyrantrum (Lv50) - Swords Dance, Dragon Claw, Head Smash, Iron Head
All these Pokemon satisfy the need of having a move with "Dance" in the name and I think better fit the whole dancing aspect of Tierno's character, for ones like Mr. Mime and Politoed it's pretty obvious, I'd imagine for Swanna and Tyrantrum you could think of it being like how among some birds the males will perform dances to attract females, I mean Tyrantrum has that fluffy collar so that could be its purpose.
You could also make Trevor's team be;
Sableye (Lv48) - Shadow Claw, Foul Play, Fake Out, Poison Jab
Heracross (X) (Lv48) - X-Scissor, Storm Throw, Superpower, Stone Edge
Pinsir (Y) (Lv48) - Megahorn, Brick Break, Rock Slide, Earthquake
Florges (White) (Lv49) - Moonblast, Energy Ball, Psychic, Swagger
Heatmor (Lv49) - Flamethrower, Giga Drain, Will-O-Wisp, Slash
Abomasnow (Lv49) - Blizzard, Wood Hammer, Earthquake, Shadow Ball
Aurorus (Lv50) - Freeze-Dry, Ancient Power, Psychic, Earth Power
Trevor's Team in this is comprised of Aurorus (which is a one-off) and several low encounter Pokemon, Abomasnow is the exception but I think if they expanded more on the Frost Cavern event him having one would be neat.
