Sylveon in Dusk Ball. I love the contrast between the bright (almost painful) pinkness of Sylveon and the explosion of darkness that erupts from the Dusk Ball.
Oh I got a lot of favorite combo but i gotta say I really love Safari Ball Larvitar, or Safari Ball x a lot of mons really. A few others would be.... (yes there's a lot more than these lol) Heavy Ball - Skarmory, Steelix Level Ball - Arcanine, Mudsdale
Cubone in a Dream Ball I saw this once and love the aesthetics. Repeat Ball and Porygon-Z. And Timer Ball plus practically anything, it's fabulous. #MissingNo
I'm not a picky person when it comes to catching Pokémon in specific balls...okay that sounded a little wrong Anyway, I do like the aesthetics of the Dusk, Timer and Premier Balls. I often rely on Dusks a lot since I seem to have a magic touch when it comes to Pokémon that are more difficult to nab.
Literally any pink Pokémon in a Dream Ball. The burst of pink is a perfect compliment for cute Pokémon!
Dive ball on Walrein. Or friend ball on Decidueye. Luxury ball for Cosmog's line for irony's sake. Get in the ball, Nebby! Dusk ball is pretty good for Pumpkaboo/Gourgeist since it's sort of a halloween color. Premier ball and shiny Absol is pretty good since the colors match pretty much perfectly.
Friend Ball Leafeon Moon Ball Alola Pix Moon Ball most everything Heavy Ball Metagross Moon Ball Deino (Something I recently found)
Eh, I'm not particular w/what Pokémon and Pokéball combinations I like, but any Pokémon that can evolve via a Moonstone belong in a Moon Ball to me.
Love Ball Mimikyu <3 Also, I always like it when I catch Legendaries in Premier Balls. Especially Shiny Legendaries
I think it's quite impressive seeing legendaries coming from standard Pokeballs! It's a testament to the trainer's luck or patience given how tough some of them can be to catch. A Wurmple in a master ball? Perfection.
Ampharos in an Ultra Ball, Metagross and the Porygon line in Beast Balls, Blaziken in Cherish Ball (aesthetic-wise) I also think Great Ball on Tentacruel/Tentacool looks good because they basically have the same colour placement
Shiny Whimsicott (and Altaria) in a Dive Ball (人´∀`*) so gorg I love this ball! And then Flaaffy or shiny Ampharos in a Love or Dream Ball... my babies.
