>>50216561In real life two kinds of animal that can breed to produce viable offspring like horses and donkeys have to be more closely related to one another than two that can’t like horses and goats. Pokémon reproduce based off their egg groups so all Pokémon in the field, monster, water 1, human-like, etc would be closely related to one another irl terms. And than there's Pokémon with two egg groups. What I'm trying to say it's a cool idea but Pokémon doesn't follow real life biology so a cladogram wouldn't look anything like the one posted.
