It looks like a Luxury Ball, though the coloring doesn't seem as dark.
I think it's just weird lighting
Yeah, I meant it's just harder to tell because of the coloring (because of the lighting). My bad. At first I thought it was a white ball, but then I realized the patterns were of Luxury and it must be grey color.

The group shot right at the end (which is what you'll see after it zooms out of the TC's screenshot) has every Pokémon all the featured characters have ever owned including released ones EXCEPT Snivy and PIKACHU.
Yes, the animators are so obsessed with throwing Eevee and Sylveon into everything they forgot to include the franchise's MASCOT in the group shot.
