>Poison
I like the defensive playstyle of most poison types and Toxic is my favorite move in the game. Not only that but poison types have amazing designs all around. Can't ever hurt to have a poison mon around.
>Bug
A very close second (might even dethrone Poison) but a type with amazing designs, fun play style, and underdog status. I always have at least one bug on my team. Gen 7 was very good to me.
>Fairy
It used to be Ice until I noticed I have an absurb amount of fairy types on my team. Fantastic designs and flexible lore (could be a cute disney-like fairy or a mischievous/malicious old fae.) My favorite Pokemon (Whimsicott) is one to boot.
