Yeah it was unfortunate that Marriland had to get a pair of two Flying-types but both Taillow and Zubat have their unique niches. It was cool to see Calzone evolve into a Beautifly because he never used Beautifly in any playthroughs before, but dang Beautifly is so good at solo'ing Brawly (dat OP Gust), just like how I did in my Alpha Sapphire playthrough.
Still concerned about how Marriland will handle Wattson, but Pickles should be able to solo that Gym given he'll be a Marshtomp by then. The battle against May on Route 110 is tough, but her Grovyle won't be an issue for Calzone or the Flying-type pair.
And isn't it funny that this is his third time using a female Zubat, and all the female Zubats he's used were all named after some food which has eggs in it. I do wonder if Quiche will turn out like Frittata and Eggpie before her and survive a good chunk of the game.
