If you are able to put natures on these Pokemon
Charmander: Timid
Gastrodon: Whatever you think would be best for him, probably going to be using him for bulk so like increase in Def or SpD
Miltank: Once Again Whatevr you think would be best, Probably going to be used as a kind of bulky set up sweeper
Porgon2: Calm
i have every pokemon, but marshadow at this moent, by i am still looking for ha pokemon so any moon or sun pokemon with an HA would bed cool, I don't care about nature or gender
Could you possibly breed me a Charmander and Whatever Porgon2 evolves from? I don't have the pre-evolution for Porgon2 but I could trade a charmander over to you from a previous Gen if you don't have one. Also what you want in return
