Pokémon Storage Cleanup

There is a somewhat hidden search syntax you can use to make Pokémon storage cleanup easier. Below is the search string I use. It helps quickly isolate the majority of undesirable Pokémon, and then you can manually inspect the rest:

!3* & !4* & !shiny & 1-4attack , 1-4hp , 1-4defense & 2-4attack , 0-1hp , 0-2defense & !legendary & !mythical & !ultra beasts & !shadow & !# & !unown & !dynamax

Under the search bar in the Recent section, you can long press on the search circle to save it with a more memorable name (e.g., Cleanse).
