Hello, i suggest to change the spawn of larvitar, and to add it to mountain zone in zafati johto, because all the pseudolegendaries can be caught in the zafari zone in their respective regions. For example :

 

Dratini : can be caught in safari kanto at least with ms.

 

Larvitar : dont appear in safari johto

 

Bagon : dont appear in safari johto but beldum yes appear

 

Gible : dont appear in safari sinnoh

 

 

I suggest if it is possible to add to larvitar a,d gible to safari zone in their respective regions, and if you want to difficult the access to pseudolegendaries until we will be the champions in that region, it is an option.

 

The pseudolegendaries only being catched after we defeat the elite 4 in each region in the safari zone, and limit the enter to the safari zone until we beat the elite 4

I agree with the Bagon and Gible one but the other 2 can be found and/or received easily so theres no need to alter their spawns where as bagon and gible should be rare and difficult to hunt.
