To be fair, every single pokemon game is easy af, unless you are a kid not knowing what to do. That is why the Locke's were invented.

I kinda want to to my Locke in SuMo, tho idk if i want SuMo that bad.
Basically, you can only use two pokemon the entire playthrough. No Potions. No Status Healing. No Healing moves(optional) Limited Poke Centers.
