What Kind of Pokémon Can You Raise If You Don't Have Money?

"Brother, can't you really raise Pokémon if you don't have money?" "Sister, to raise Pokémon, you need to buy Poké Balls, you also need to take the hunting license, the trainer's license, and a lot of seven or eight certificates... You have to feed Pokémon feed every day. If you want to breed powerful Pokémon, you don't know how high the investment is. Do you think the gold-sucking beast is a joke?" "Then... Then I'm not a trainer, and I don't train powerful Pokémon. I just raise one for myself to play with." "Then when you are walking on the road, a trainer will stop you and force you to fight. Then he will beat up your Pokémon and take away your money. You will have to pay for the medical expenses yourself." "Uh-huh, brother, then I won't raise Pokémon." "You can raise it, you can raise it, little sister, I'll sign you up for the Pokémon Trainer Genius Class." "Is this genius class you mentioned formal? You won't sell me out, will you?" "Haha." "Brother?"
