The game should guaruntee the probibility of getting a starter rarity monsters. So if the odd are 1/200 then by the end of 200 time you should get a chance at the monster. Its annoying being in the right spot for select rare monsters but not seeing it once out of 4000+ battles
There is a fail safe at 2000 battles
I can literally guarantee that you have not hit 2000 battles in the same spot
They ALWAYS appear before you even get close to 2000 battles.
And technically, it’s .5%. It still makes it surprisingly easy for them to appear
Make sure you’re doing other stuff while you’re waiting
