Pokéballday: Pokéball

Welcome to Pokéballday.
A new Pokeball inspired by a Pokémon every day.
801 Pokémon (And also all the new Pokémon of Alola, and MissingNo.).

The plan is dedicate one of two hours daily crafting a new Pokeball. Study and simplify them.

I'll start with the simplest thing, the Pokéball.

See you tomorrow!
