Please read through the whole OP when making a Proposal post.Seeing doughboys map makes me think that like in Johto and Kanto the town should have a river to the south therefore I propose a couple of mons to catch to the south of starter town (also can druddigon be an event legendary :p. )
Starter Town
Surfing: Horsea (15-20), Mantine (18-23), Seadra (25-30), Tentacool (15-20), Tentacruel (25-30)
Reasoning: there are not that many non legendary non event surf mons that are even slightly viable but this is a decent mix of options.
Fishing
Old Rod: Magikarp (level 5-10)
Reasoning: Old Rod should catch karp on all routes.
Good Rod: Magikarp (15-20)
Reasoning: see above
Staryu (15-20)
Reasoning: A very good competitive water type and is usually caught in seas with a good rod.
Alomomola (15-20)
Reasoning: Eases grinding lots after getting the good Rod.
Super Rod
Gyarados (35-40)
Good attack EV fodder for quick grinding and is always caught with super Rod
Alomomola (35-40)
Reasoning: Keep the grinding train going.
Need some more super rod ideas but love this idea :).
Remember:
-Only 1 Pokemon can be proposed in 1 post
-Proposal must be in the format described in the OP
-All Pokemon a route must be either on the OU viability list, or a parent for a certain move (or otherwise useful for raising)
Tentacruel is not on the list.
For the first town, I'll entertain the idea we have water, and allow 7 Pokemon
