Best Psuedo-Legendary

How do you define pseudo-legendaries? Is Mimikyu just here as a joke?

I tend to define them as non-legendary Pokémon with high base stat total final forms, approaching or rivaling actual legendaries.

Generally I find them a little boring. Their power tends to be their main selling point, so I feel a lot of their designs are fairly bland. Even though I like dragons, both as Pokémon and in other media, I find the dragons amongst the pseudos pretty uninspiring. And of course they are overused in competitive, which leads to boring, samey team compositions.
