Serious reply here:
Battle style is turn based, speed and styles do not exist mainline.
Expect alot less emphasis on catching / battling wild pokemon. 1 catch fills the dex. Battling is only for exp purposes.
I'm ngl pokemon battles in the main games are gonna be way harder than PLA, each PLA battle i was able to force through underleveled with shitmons, you do need some (elementary level) strategy to win most times.
Alot more hidden values and hidden ways to evolve pokemon. Spinning, holding the switch upside down, half killing your pokemon, have alllll been evolution methods.
If there's anything specific you'd like to know I'm sure another srsbro could answer or assist
