>>12054207Pretty much just those 6. It is a nuzlocke in the sense that faint = death and that I can only catch the first encounter on a route, but I have additional restrictions:
1. I can only catch the first encounter if it is 100% certain that the first encounter will be that encounter.
2. I can only catch the first encounter if it is 100% certain that I will catch it.
This leads to a state where the only wild pokemon I can catch is Magikarp or Tentacool, as Old Rod and Surfing have the 100% encounter requirements, but I can only catch one, because the 100% catch requirement means I have to use a Master Ball.
The others have to be obtained from gifts in-game, and fortunately are all in areas where I don't encounter other pokemon in the area, so they can count as my first catch for the area.
